Being a romantic at heart I love to believe that my Scotish ancestors supported William too!
I guess a coat of arms granted in Edward's reign must mean the grantee made him a happy chap, showed him the desired loyalties, and all that! Given the number of direct ancestors we all have by the time we get back to those centuries it stands to reason Edward is everybodies grandfather somewhere in their tree (definately a relative at the very least), and King Robert Bruce the same. The mind boggles at the thought of our ancestors being involved in such heinous battles with each other.
My ancestry is mainly UK, with some Swedish & Moravian in there too. I suspect there is also a smidge of native Jamaican, but will never be able to prove it as the male line stopped at my maternal grandfather who is no longer alive. The bloodlines of those of us descended from emigrants do tend to be like a melting pot of cultures! It's why I call my tree Aotearoa Soup! ('Aotearoa' being the Maori name for NZ)
lol ... maybe your ancestors did sing and look like the Irish women on PBS
Heres a couple of interesting articles on names pre & post Norman conquest ....
