This is an update on my earlier blog on my DNA tests. Since the blog was written in 2014 four other Grannums have undertaken DNA tests and we all have close paternal matches – in addition three of them match as genetic cousins. Because of the genetic evidence suggesting that were possibly related within about 5 generations we used personal and online indexes and linked documentary evidence to join two previously unknown family groups, rewrite the family tree for one family and take both families back several generations to the 1840s. The testers have joined the FamilyTreeDNA Grannum project at https://www.familytreedna.com/groups/grannum/about
I had heard about DNA tests as a genealogical tool for many years but costs were quite high and I was not convinced of their value to my research or for wider Caribbean genealogical research.
However, because of documentaries such as BBCs Motherland in 2003 Caribbean genealogists increasingly asked me if DNA tests would be useful for their research and help them reconnect with their African ancestors; I added several slides on DNA to my talks.
As the price came down I thought about taking a test – so that I could understand what was involved and if the results could actually help someone to extend their family tree or link them to their ancestral home. I was also curious if such tests would help answer these three questions:
- I do not know where my Grannum / Cranham ancestors came from and so maybe these tests would help to narrow down place of origin
- Maybe I would find a match with someone in Europe which would help me to continue my research
- My family had lived in Barbados for over 250 years. Was I mixed-race?
