Joan Keymer-Thomas Burridge Dorset 1727
We have had our mitochondria DNA done and we are U5 Haplogroup and takes us to the Scandinavian countries, although she ended up in England. If I recall, they were weavers and probaby immigrated to England
It is a very old haplotype, but if you look that up, you might find that of interest.So, we are most likely connected. But, I have nothing further back than Joan Keymer.And, I do not know anything about oursurname . You could go to the following web site.ehttp://www.surnamedb.com/Surname/Keymerither.
Wish I could be of more help.Bonny
