Tracing your Racicot family back into the past with Y-DNA testing

I am writing to you on behalf of the Roscoe Family History Y-DNA Study -- an informal, private group of American and European researchers for the different families of Roscoe, Rascoe, Rasco, Ruscoe, Rosko, and similar spellings including Racicot, Rauscoue and Rascon. As a retired lawyer researching my grandmother's Rascoe family, I have joined with these other researchers in an all-volunteer project to trace our Roscoe and similar spelling family lines past brick walls and back through the centuries with Y-DNA testing. Our investigation applies Y-DNA technology to develop new tracing information on the different Roscoe (and related spelling) families, and you may be interested to hear about our investigation and our recent progress.

Our study uses Y-DNA profiles to identify and trace the different Roscoe (and related spelling) family lines in America, Europe and elsewhere back to their earliest detectable origins, and to find and either prove or disprove relationships between and within these family lines. Y-DNA testing measures specific characteristics on the male tester's Y-chromosome that are genealogical markers -- passed down on the direct paternal line from a father to his son, to his son, to his son, etc., with relatively few changes or mutations over the centuries. This chain usually follows the surname back through the generations many hundreds of years ago to the time in history when surnames were first adopted, and then follows the genetic profile beyond. A second test is recommended to confirm and verify each line back to the Most Recent Common Ancestor and preclude a possible DNA sidetrack in the expected paternal line due to an unrecorded adoption, friendly neighbor, or research mistake. Y-DNA technology now offers the ability to identify the distinctive profile for each genetically different Roscoe family, to estimate how long ago the Most Recent Common Ancestor for near-matching testers on that line probably lived, and to find indications of where each family came from originally.

Female Racicot descendants and male Racicot descendants not having the Racicot surname can participate actively in our study by encouraging Racicot-surname male relatives to test and represent their common Racicot family line profile.

In the past six weeks our study has made progress by developing five new Roscoe-related tests:
(1) an Illinois Roscoe, who reportedly traces back to William RUSCOE (1594 Essex, England - 1682 Jamaica NY), who was reportedly the son of immigrant JOHN ROUSCOUE, alien, taxed in Essex in 1545,
(2) a Bedfordshire RUSCOE who traces back to the Cheshire Ruscoe family (possible match for the Essex Ruscoe tester),
(3) a Lancashire ROSCOE born in Bolton and now living in Yorkshire,
(4) a California ROSCOE and British citizen, whose father and grandfather were born in Blackpool (possible match for the Bolton tester), and
(5) the Pennsylvania Roscoe son of a Slovakia-born ROSKO (possible remote-match back to our Virginia Rascoe early I2a origins in the Balkans).

Our Roscoe study is very much interested in developing a Racicot test because we understand that for some family lines Rasco or Roscoe can be an anglicized or Americanized version of Racicot. We would like to find out whether the French Racicot family is related to any of our English Rasco and Roscoe lines we are developing. Also, we understand that some of the Rauscoue-Rouscoue-Ruscoe immigrants to England in the 1500's were possibly Flemish or Dutch Huguenots in flight from religious persecution. It would be fascinating to see whether the French Racicots were related to the Rauscoue-Rouscoue-Ruscoe line we are developing in our testing, or the Spanish Rascon family we would like to develop, and so on.

The Y-DNA testkit for Roscoe- or Racicot-surname males, swabbing the inside of the cheek, is easy and takes only a few minutes -- 3 swabs at 60 seconds each. It comes in the mail to the tester's home. No blood is involved, and no medical or other information is recorded or obtained. The tester's private testkit page for tracking his test results and matches is password-protected. Privacy of test results and samples is protected by the strict protocols and guidelines followed by the testing company, as required by federal and state law.

We use the leading family history testing company. It has the largest Y-DNA databank to compare with our test profiles due in part to its collaboration with National Geographic's Genographic Project, systematically testing haplogroup populations all over the world to understand and trace family origins. Over 223,000 tests world-wide show how American and European family historians have recognized the advantages of Y-DNA testing. No one with our Roscoe study group owns any interest in the testing company or any related entity, or receives any type of compensation in connection with the testing.

For more information and links to the testing company FAQ, you can visit our Roscoe Y-DNA group website at or The Roscoe family history forum in England with explanatory articles at and let me know if you have any concerns or questions.

Our Y-DNA methodology has the potential to move beyond brick walls in traditional research and to discover specific, reliable Racicot family history information of unique value that cannot be obtained from any other source with any amount of effort or expense. Please let me know if you or any Racicot-surname male you know might be interested in learning more about representing the Racicot family in our investigation and helping us trace our different Roscoe and Racicot families back as far into the past as possible.

Looking forward to hearing from you,
