Welcome to the Cruwys/Cruse/Cruise/Crewes worldwide DNA project. Anyone with any of the many variations of the surname listed above is invited to participate. The project was set up on 26th September 2007. We now have project members living in nine different countries: England, Ireland, Scotland, France, America, Australia, Canada, South Africa and Thailand. A substantial number of major lines are now represented, thus increasing the likelihood of a match. Outline pedigrees for all the project participants can be found on the results page.
The DNA project is run in conjunction with the Cruwys/Cruse/Cruise one-name study, which is registered with the Guild of One-Name Studies in London. Further information about the study can be found on the Cruwys profile page. The results of ongoing research are published on the project's blog, Cruwys news. For a simple introduction to DNA testing you might like to read my article which was published in the September 2008 issue of the Berkshire Family Historian and which is now available online. A more in-depth article, entitled "A Practical Guide to DNA Testing" appears in the October 2009 issue of Family History Monthly. See also my presentations DNA for Beginners: The Three Tests and Chromosomes, Conquerors and Castles: DNA Testing and the Cruise/Cruse/Cruwys one-name study which are linked on my profile page on the Genetic Genealogy Ireland website. Further information on genetic genealogy and additional resources can be found in the ISOGG Wiki.
For the purposes of the DNA project we are using the Y-DNA test, which tells you about your direct male line, that is, your father, your father's father, your father's father's father, and so on back in time. To participate in the test you should therefore be a male with one of the surnames shown. If you believe there is a CRUWYS, CRUSE, CREWES or variant in your direct male line, although you have a different surname, you are also welcome to participate. If you are female, you will need to ask your brother, father, uncle, cousin or other male relative to take a test on your behalf. We are using the 37-marker test which is usually sufficient to confirm matches within a genealogical timeframe. If you are seeking matches with other surnames or are interested in exploring your deep ancestry you should order the 67-marker test.
The project is now able to sponsor free Y-DNA tests for CRUISE men with a documented ancestor on the direct paternal line who was born anywhere in the British Isles. If your ancestor was born in Ireland please see the Cruise Men of Ireland flyer here. If your ancestor was born in Great Britain please see the Cruise men of Britain flyer here. Alternatively you can contact the project administrator for further information. A limited number of free Y-DNA tests are also available for CRUSE, CREWES, CRUWYS men from documented British lines which are not yet represented in the project. Please contact the project administrator if you think you might be eligible.
Whether male or female, you may also be interested in learning about your direct maternal line, that is, your mother, your mother's mother, your mother's mother's mother, and so on. Both men and women inherit mitochondrial DNA, although only women pass it on. The low-priced mtDNA Plus test will give your haplogroup assignment (your branch on the human mtDNA tree) and can be used for low-resolution matches. The full mitochondrial sequence (FMS) test is recommended for finding matches within a genealogical timeframe and for a detailed subclade assignment. The project accepts mtDNA results from anyone who has an ancestor in his or her direct maternal line with the surnames Cruse, Cruwys, Crewes, Cruise or variants.
The project is also collecting Family Finder results from both males and females with these surnames anywhere in their tree within the last ten generations. In order to understand how the Family Finder test works see my blog post The new Family Finder test from FTDNA.
The DNA tests used for genetic genealogy contain no personal information, and the tests are quite different from those used by forensic scientists in criminal investigations and by doctors to identify paternity. Furthermore, the test itself cannot identify a unique individual as close male members of the same family (brothers, uncles, cousins) will in all probability have identical results.
Tests ordered through this project are charged at the special group rate which provides a substantial saving on the standard FTDNA price.
If you have already had your DNA tested with Family Tree DNA as part of a geographical project or another surname project (eg, CREWS or CRUISE) you are welcome to join this project too. There is no extra charge for joining multiple projects. Simply click on the "Request to join this project" button at the top left, enter your kit number and password and your results will automatically be included in this project as well.
If you have already tested with the Genographic Project you can also join this project at no extra charge. To transfer your results use the direct link on the FTDNA website.
The Cruwys/Cruse/Cruise/Crewes DNA Project is an independent genealogical research study run by a volunteer project administrator. The group administrator receives no payment or incentives from Family Tree DNA or from any other organisation or institution. There is no guarantee that every participant will match anyone in the DNA project or in the wider Family Tree DNA database.
Member information and data obtained from the Cruwys Project must be attributed to the project, the administrator and Family Tree DNA. Please notify the administrator when using data for public or private research.
