I am Alan Brigham (middle name Scott) and I one of your UK Brigham's. I was very intrigued by the discussion on the Brigham origins and family tree.
My father is Ian Adams BRIGHAM and my grandfather was George Henderson BRIGHAM.Now, according to our UK branch of the BRIGHAM's, we have more scottish ancestry than Yorkshire. Yes the name BRIGHAM certainly has a Yorkshire (English) origin. But according to grandfather, as the border between England & Scotland moved so much, we were more Scottish than English. Indeed, two items of information can (but not necessarily) point to this. (a) George Henderson BRIGHAM was a life long peer and "Freeman" of Berrick-on-Tweed, a uniquely Scottish character town. And so were his ancestors. And (b) there are two village's of BRIGHAM, one on the East and one on the West. The Eastern one indeed can be (might be) associated with the city of York and Yorkshire but teh Western one, far West almost above Wales but definitely always in Scotland, is very Scottish.
All depends from which one our American relatives hail from.
Anyhow, there is my little unprofessional comment (as I have never reserached it).The reason I came across these discussions from the US is because about 3 years ago I started receiving emails from a US Brigham family, specifically cc from Mary Brigham, Carol Brigham and Patricia Brigham. I never bothered to look into it that much and cannot even remember the email contents. However, these names remain in my address book. Interesting...
