We just gotta keep diggin'
The Family Tree DNA organization has the largest ancestry DNA database in the world.
There is a Gledhill DNA Project which is for Gledhills and anyone who has a close Gledhill relative. You are strongly encouraged to become a member of this project.
"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-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." (Family Tree DNA)
