I-M223 haplogroup observations:
   synonymous with M223

There is another haplogroup that is closely related, and is likely a "subclade" of M223, and that is the "Irish" marker of I-L623.  For our current purposes, we are assuming that all L632's are also M223's.

Detailed statistical analysis of the mutational patterns for our current (Oct 2018) members suggest that they all share a common ancestor from sometime in the last millenium, time frame still to be resolved, but possibly 1400-1700.

All of the M223s thus far tested have ancestors in Ireland, generally the northern counties of Ireland.  One member still lives in County Donegal.

We know that the Ralston/Rolston/Roulston/Rolleston surnames did not arise in Ireland, but rather in England or Scotland.

It seems most likely that these families (or this family) emigrated to Ulster or surrounding counties as part of the Plantation system beginning in the early 1600's.

So where did these Irish Rolston, Roulston, and Ralston families come from?  This set of facts allows for several possibilities:
--That these really are Scottish Ralstons.   But current known Paisley/Ayrshire/Kintyre Ralstons are testing as a different haplogroup (see notes on RM269).  Yet there may have been more than one Scottish lineage of Ralstons.
--That these are really English Rollestons.   We are still waiting for our  first test results from a proven Rolleston.
--That a single non-Ralston male or cluster of related males in the northern counties of Ireland adopted the name Ralston, perhaps because of who the worked for or some other sociologic reason.
--That a non-Ralston male was adopted by a Ralston family.  In agrarian times, two hundred years ago or more, many adoptions occurred without official paperwork, with neighbors adopting orphans after their parents died.  In many cases, the child was never aware, and always assumed that the parents who raised him  was also his birth-parents.  (I am using the male pronoun, because yDNA is testing only for male Ralstons/Roulstons)
--And of course, the possibility of a birth out of wedlock, which likewise was commonly hidden from the offspring.


These related families have a remarkable diversity in the spelling of the surname.  Even though we have evidence that they descended from a single family.  Spelling variations may have been due to differences in pronunciation in different countries or counties.  But may have simply been due to the nature of literacy at the time, and the fluid way in which many English words were spelled as they sounded to the listener.   Surnames were handed down  orally long before they were written down.
These M223 surnames include:


R-M269 Haplgogroup
       Synonymous with M269

There is one current subclade for this haplogroup, determined by more advanced testing, such as "Big-Y" testing offered by the FTDNA company.

These should still be considered M269, but have a novel title of R-BY15421, or the shorter version BY15421.

These Ralstons seem to share a common spelling of "Ralston" and share a background in Paisley, Ayrshire (just south of Paisley), and a branch that colonized the Mull of Kintyre in the 1600-1700's. 

The current assumption is that these Ralstons arise from the "Ralstons of that Ilk" that, according to legen, arose east of Paisley.   The original Paisley lands were swapped for an estate in Ayrshire, near Beith.

The story of those Ralston's is related in this History of Ayrshire book, written about 170 years ago:    [start at about page 265]   https://archive.org/details/historyofcountyo01pateuoft/page/264


Some of these M223 Ralstons (various spellings),  fall into known family groups in the US and Northern Ireland, including County Donegal. 

Likewise, many of  the M269 families fall into known family groups in the US, Scotland, and New Zealand.  It seems likely that there subsets of this haplogroup spread across the English-speaking world, including Canada, New Zealand and Australia.

To respect privacy concerns, we cannot openly publish these known families.  But if you join the project, we will make efforts to see that you are aware of your family group.
