The D'Arcy / Dorsey/Darsey/Darcy/Dawsey/Dossey/ Surname Project


Established 2002 - This project is organized, administered, and paid for by family members for the purpose of linking ourselves to the past.

The purpose of this project is to analyze Y chromosome DNA of males with the surnames Dorsey, Darsey, Darcy, Dawsey, Dossey, and D'Arcy to learn more about the interconnections between and within families of those surnames. In our culture, surnames are handed from father to son. Happily, a father also passes a copy of his Y chromosome, virtually intact, to all of his sons. This makes the Y chromosome DNA (Y-DNA) a kind of biochemical signature for the surname. In the last ten years or so, (relatively inexpensive) procedures have been developed to characterize specific segments of the Y chromosome DNA. Now there is a growing movement within the genealogy community to utilize this procedure to compare the characteristics of the Y-DNA segments to identify and define patrilineal lines.
