About us

In May 2018 the host 'WorldFamilies' closed down and this project is now hosted by FamilyTreeDNA (FTDNA).

Its focus is on yDNA testing – which correlates directly with the genetic paternal line of every male – which often (but not always) correlates with a man’s surname.  We welcome all with a Project Surname (and similar names which we haven’t listed) plus the men who are yDNA matching them at 37 markers or more.  

Females with autosomal results ('Family Finder') are also welcome, but it is best that the ladies also request their siblings or fathers or uncles or male cousins to test.  Y67 is a good test to start, but Y111 is better.

FTDNA also accepts Ancestry transfers but an FTDNA test gives a more in-depth result.

We encourage project members to provide their Earliest Known Ancestor & Pedigree and allow public display of their earliest known male paternal ancestor, their ySTR & ySNP results.  We also recommend that they respond to contacts from other researchers.
