Inspite of my Japanese name, I am descended from a number of east coast families, including the Tyr/a/e/ee/er family.
It is a matter of commonsense that, with a name with as many spelling and pronunciation permutations as that of the various Tyr/a/e/ee/er families of the English-speaking world, we are probably dealing with more than one DNA male-line lineage. Matters are further confused by the poor survival rates and often ambiguous nature of records from before the 19th century. This has complicated matters for all researchers of the Tyr/a/e/ee/er families in particular, because so many of them seem to have had their origin or stayed long periods in the so-called burnt over counties of Virginia.
I am proposing a project of the nature of one I am doing for the Cotten/on families. Last year, with the cooperation of three other individuals (of whom, one is no longer alive), I started a y-chromosome signature project of people having a male-line Cotten/on descent. It has already proved itself to be of great value to the participants and has significantly refined the nature of Cotten/on genealogical studies which center on the southeastern United States.
I need volunteers who will undergo the necessary DNA testing and share their results with me for immediate inclusion into my website on a separate Tyr/a/e/ee/er page. For further information, please refer to my website at "http://family.nf". Although everything deals with a different set of surnames, the style and methodology would be exactly the same for a Tyr/a/e/ee/er Y-Chromosome Signature Table. If you have any questions, please contact me either on this genealogy forum or directly at my e-mail address "firstname.lastname@example.org". Thank you.
