Welcome to the Debenham Surname DNA Project which was started in January of 2010. All Debenhams and variant surnames are welcome to take part in this exciting new project. Large groups of people with these surnames live in England, Wales, Australia, and the United States. Over time spelling of the name Debenham has created many different variant surnames. Supposedly each of the variant family surnames are descendants of families that lived in the little Hamlet in Deben, England. We now know they do not all descend from Lucas de Debenham who lived in Debenham, England in 1165. Thru Y-DNA testing we can now find our true family lineages, no matter how our last names are spelled. We now have twenty seven members and seventeen different family lineages which are listed in the Goals section of this website. At this time we have four confirmed Family lineages that we know did not go back to Debenham, England, The Seneca Dedmon/Manley Line, The Norman Viking Dedmon/Tipton Line, The John Dedman Line and The Daniel Debnam Line. Thru Y-DNA testing it has now been confirmed that the Sapiston Line and the Redgrave Line identified by Frank Debenham are one and the same and as a tribute to Frank Debenham we are calling this line the Frank Debenham line which he was a member of. Y-DNA is passed from Father to Son only from generation to generation without change, except for mutations. This technique allows us to identify which family lineages we are not related to as well as which ones we are related to. Male descendants from the Debenham Line or the variant surname Families may become members of the project by taking a 37 marker Y-DNA test with FamilyTreeDNA. Each member will share their known father to son lineage in the News section of this website to help with the grouping of the families. We encourage females to become members of our project by having a male relative with the Debenham or variant surname take the 37 marker Y-DNA test with FamilyTreeDNA and join our Project together thru their test. Taking the Y-DNA test is very simple, you can view a video by doing a search on the internet: "How To Take A Family Tree DNA Test - You Tube". The Y-DNA test will preserve your family's Y-DNA sequence for future generations should all of the male's in your lineage dissappear. Please consider giving a financial gift to the general fund of our project at the bottom of the page. The money will be used to help with the cost of the 37 marker Y-DNA test for new members who would not otherwise join our project.
