Description
The Roache DNA Project, which includes all variant spellings, is for people who are interested in extending their family history beyond the traditional genealogical paper trail. Since surnames came into existence, diverse spellings have evolved (Roche / Roach / Roache, etc). For the most part, and contrary to popular opinion, these variations are of little significance.
The Y chromosome (Y-DNA) provides a powerful tool for discovering ancestral male lineages because, unlike other chromosomes, this DNA molecule is passed down directly from father to son. Only males inherit the Y chromosome, therefore surname analysis can only be performed on male DNA. Females who would like to check their direct paternal line can have a male relative with the Roche /Roach surname order a Y-DNA test.
By comparing the Y chromosome from different Roche /Roach families, it is possible to judge how closely they are related. If their genetic codes are very similar, we can say that they share a common male ancestor in the recent past. The more differences in their genetic code, the more generations have passed since their last common ancestor.
Requirements
A Surname Project traces members of a family that share a common surname. They are of the most interest in cultures where surnames are passed on from father to son like the Y-Chromosome. This project is for males taking a Y-Chromosome DNA (Y-DNA) test. Thus, the individual who tests must be a male who wants to check his direct paternal line (father's father's father's...) with a Y-DNA12, Y-DNA37, Y-DNA67, or Y-DNA111 test and who has one of the surnames listed for the project. Females do not carry their father's Y-DNA. Females who would like to check their father's direct paternal line can have a male relative with his surname order a Y-DNA test. Females can also order an mtDNA test for themselves such as the mtDNAPlus test or the mtFullSequence test and participate in an mtDNA project. Both men and women may take our autosomal Family Finder test to discover recent relationships across all family lines.
