Paul Switzer Paul Switzer has a question!
February 24 @ 3:31am
I recently had SNP's "counted?" for my brother Paul Switzer. He is no longer I-M253. He is now I-Z59. I am being advised to upgrade further and have more SNP's "counted". Would you advise me to spend a further US$115 or so for this further upgrade? Agnes Porteous 1789 Spott - 1855 Lasswade is our 3rd great grandmother. Her father Alexander Porteous b1765 Spott, East Lothian is our 4th Great Grandfather. Myra Keay (nee Switzer)

Hi Myra. First off, the SNPs and the Y-dna assignment for your brothers test does not relate at all to your Porteous ancestry. Your brother's y is only coming down his direct paternal line of ancestry from his father's father's father' etc. That means that your ancestor Agnes Porteous, as a female, could not contribute to that Y-dna.

Hi again Myra, I had a look at your brother's ydna match and I see that he has a great close match at Y-111 where he is just a genetic distance of 2 off from Thomas Switzer. This means that Thomas and your brother will sharea paternal line ancestor somewhere back in time. Looking at your brother's Family Finder results, I see two matches who share Switzer ancestry. One of them, for Natalie Ellis Aspden has a Switzer line that goes back to Limerick Ireland like yours and like Thomas Switzer's and which ties into each other. If you haven't already, you should consult with these two individuals and figure our where your Switzer line connects to them. Likely the connection to Natalie is closer based on the fact that she is a Family Finder match and Thomas isn't (but is a Ydna match to your brother). Good luck. Jason

Switzer is a name that also comes up in my ancestry. I can't pin it down but I suspect it is linked to the Palataine Irish, or descendants of refugees from the Rhine region who settled in England and Ireland during the Napoleonic wars. If it ties in with my DNA links to Porteus that would be interesting.

An important notice. Following recent updates to FTDNA site since the mandated upgrades that the new European Union requirements dictated related to privacy, you have likely been required to update your settings at the site. Some of you have selected the option to grant Project Admins only "Group Project Access Only" for their personal Project preferences. If members retain that setting, I am not able to see or do anything to help members out looking at their data :- * I cannot compare their results; * I cannot go into their home page; * I cannot see what level testing they are at; * I cannot see what tests they have ordered. Essentially, this level of sharing reverts access back to the same level almost as anyone who hasn't joined the project. I would therefor ask for project members grant project admins "Limited Access" To do this, log into your FTDNA personal home page and hover your cursor over your name on the top right hand side and click on “Privacy and Sharing” and work through the privacy options. When complete, click on the tab right next to the “Privacy and Sharing” called “Project Preferences”. For every project that you have joined, please click on “EDIT” then grant the admins ‘Limited Access’. Thanks to you all for being part of the project. Jason

This picture is a called a McGuire Chart. It is a twist on a descendant chart in that it shows how much each person who have done an atDNA (autosomal dna) test share dna between each other. Shared dna (measured in cM) is indicated (as is the relatedness ie. 3C or similar) where the two people cross vertically and horizontally. Some of you may know that I have been trying to recruit folks to join our Porteous surname project and to transfer their test results from one company to another or to www. gedmatch.com. This is the type of thing that can be developed. The Chart is primarily descendants of Archibald Porteous and Grizel Robison (#925) but includes a few other folks who are either speculative children of Archibald and Grizel or are descended from branches of the Porteous family #8 (Thomas Porteous and Anne Brown) who I believe my #925 falls under. The three siblings in the middle right are me, my brother and sister. The shared dna lends to this theory until I can get a direct male of that family to test and to come up a match to myself. The chart was generated using matches to my grandfather's 1C W.H. who happens to have the most Porteous cousins as shared dna matches as well as a couple other key matches who also have dna matches to a wide span of my cousins.

I was mostly trying to convey the description of the chart. at the point where two people intercept vertically and horizontally, it states the degree of kinship ie. 3rd cousin or 2nd cousin etc, and the amount of shared dna in cM. If enough people from a Porteous branch have tests done, I can generate a similar chart quickly showing how each relate to each other and how much dna they share.

Jason - I hope it is OK to share this here. Finally got around to adding Family Finder package to my Uncles y-dna results. I wasn't clever enough to do so whilst the last FTDNA sale was on but I did find a discount via Groupon. First time I have ever used that website so was a little skeptical. Relieved that it all worked OK. I just purchased FF for just $66 ($65 via Groupon and $1 ftdna) rather than the usual $89. If you are wanting to add Family Finder to your results and don't have a current discount code from FTDNA, then give Groupon a go. I'm not sure when this offer will expire, but it worked for me today. Noni https://www.groupon.com/browse/chicago?lat=41.8795&lng=-87.6243&address=Chicago&query=familytree+dna&locale=en_US

I haven't ever found a discount coupon for any of the ftdna tests. I will keep it in mind next time I buy. I usually try to buy during the holidays that they go on sale. I'm looking forward to seeing what your uncle's test might reveal. It will also help you sort your own matches. If you edit your gedcom on your own account and add in your uncle, ftdna's system will assign all your matches who share dna with you and your uncle to that appropriate side of your family. Good luck. Jason

What is the difference between an SNP and an STR? An SNP is a single nucleotide polymorphism. That means that it is a single, small change in your DNA code. These changes are rare. Once they happen, they seldom change back (back mutate). An STR is a short tandem repeat. This is a place in your DNA code where a letter sequence is repeated. For example, AGTAAGTAAGTA is three repeats of the sequence AGTA. STRs have a faster mutation rate. When they change, it is an increase or decrease in the number of repeats. STR values change back (back mutate) more commonly. If you are interested in your ancestry that goes beyond where traditional paper trails end, you should focus on SNP testing. If, however, your primary interest is in the most recent generations of your family history (1 to 15), testing additional STR markers is a good investment. SNPs offer a definitive answer to a potential relationship. When one person is positive (derived) for an SNP and the other person is negative (ancestral) for the same SNP, they are not related in genealogical times. On the other hand, if both men have matching SNP results, their STR (short tandem repeat) marker results determine how recently they are related.

Is it better to get an SNP package or to increase testing above Y67 (i.e. Y111) to help determine the relationship to another member?
Jason Porteous
June 23, 2017 @ 6:27pm
At this time, upgrading to 111 won't do much for you as all 5 of your matches at y-67 have only gone as far as 67 markers. If you upgrade to y-111 the chances of some new match to you who isn't already a y-67 marker match is slim to none. You might contact Andrew Porteus or Doug Porteous and enquire if they are interested in upgrading. If you go with an SNP package you will for sure make your way further down the human y-dna tree and get closer to you terminal SNP, however I'm not sure if you will make any further progress on your genealogy research. I wanted to mention that you might wish to consider joining the Facebook group called "Porteous Family Research". There are many many Porteous families who are represented there and you might make contact with some from your own branch who you might not know of. Lots of good discussion and sharing of information. Jason

Let's suppose I contact Doug or Andrew. Which is preferable Y-111 or SNP package and does confidence improve.

I'm not sure if the accuracy improves. I've attached the TiP prediction write up between myself and Ian Murray Porteous using 67 markers and then 111 markers. I suppose the 111 is more accurate as the prediction lowers the likelyhood of a common ancestor at 12 generation from ~97% for 67 markerrs to ~90% using 1111 markers implying that our common answers is further back in time. It doesn't however provide a lot of new information. I expect if many more men tested at 111 markers and were matches to me, it would allow for an actual tree to be built around all the various mutations that were common or not between members of the group. In comparing Y-DNA67 markers, which show 3 mismatches, the probability that N51333 - Mr. J. Porteous and 245670 - Mr. Ian Murray Porteous shared a common ancestor within the last... ...4 generations is 45.55%. ...8 generations is 84.97%. ...12 generations is 96.89%. ...16 generations is 99.45%. ...20 generations is 99.91%. ...24 generations is 99.99%. * Assuming N51333 - Mr. J. Porteous and 245670 - Mr. Ian Murray Porteous do not share a common ancestor in the last 1 generation. In comparing Y-DNA111 markers, which show 6 mismatches, the probability that N51333 - Mr. J. Porteous and 245670 - Mr. Ian Murray Porteous shared a common ancestor within the last... ...4 generations is 12.11%. ...8 generations is 60.43%. ...12 generations is 90.12%. ...16 generations is 98.28%. ...20 generations is 99.76%. ...24 generations is 99.97%. * Assuming N51333 - Mr. J. Porteous and 245670 - Mr. Ian Murray Porteous do not share a common ancestor in the last 1 generation.

William Porteous William Porteous has a question!
April 14, 2017 @ 4:29pm
While FTDNA predicts my Y haplogroup to be P37 the NG project has it as L161. How do I get this information into FTDNA.
Jason Porteous
April 22, 2017 @ 11:59am
The NG project has narrowed down your y-dna haplogroup to one that is more specific then the P37 general branch that comes as a general prediction with your 67 STRs marker test. Since FTDNA does the testing for the NG project, I'd send them an email asking if they can add the NG testing results to reflect on your y-dna haplogroup results. They may not just because NG and FTDNA are not synonymis companies, but its worth trying.

Hi folks. I don't know if I've passed the message on to you all about this or not, but for those that haven't heard about the 3rd party site www.gedmatch.com, it is a site where folks can compare their results to other testers from the other dna testing companies like 23andme and ancestry. Also, it is a site that allows you to see match information for those people who share less than the minimum required amount (20 cM) that Family Finder requires to be considered a genetic cousin. This allows you to find cousins that you wouldn't otherwise find. For me, it is very useful to see how those members of the Porteous surname project might match with each other. If you haven't uploaded your Family Finder results please consider doing so! If you do I may be able to zero in on common small sections of autosomal dna that connects different branches of the famil together. Jason Porteous

As most you may have noticed, you probably got an email from the FTDNA site advising of their Holiday Sale that begins today. You should also have gotten notified of a discount coupon that you can see when you login to your account. For those who are thinking about purchasing a particular test, please let me know which one you are interested in. I have 5 or 6 accounts for my own relatives that I manage which receive coupons. Most are not going to be used by me and I may be able to share the coupon with you if I know you are looking for a particular test. As an example, I have a 20% discount in my own account for the Ydna 37 test which will save about $28 off of the sale price which is I think $129. So that brings the price for the Ydna 37 down to about $100 compared to the regular $169. Please email me if you are interested in getting a coupon for a specific test and I will try and find one to pass on to you. At the same time if you don't believe you will be using any of your coupons and you'd be willing to have it passed on to someone who could use it, IF YOU LET ME KNOW I would be happy, as the project administrator to pass details on your coupon to those who could make use of it. If anyone has any questions about the sale or about the project please send me an email or post to the project blog and I will try to answer. Jason Porteous Porteous surname project administrator
