Just saw your posting on the genealogy.com page and as I am researching my (English) Brewer family the following might help
1. There is an old English folk rhyme called "Widdicombe fair" I knew as a child. It contains a list of surnames and christian names that by tradition are always used with that family name .. the refrain is .. With Peter Gurney, Peter Davey, Bill Brewer ...(Forgot the middle) and Uncle Tom CObley so that I am Colin William Brewer My dad was Geoffrey William Brewer etc etc
2. Some English Brewers got their name from Norman aristrocrats called the De Braose's who were active in Sussex just after the Norman conquest
3, The name seems to have originated in the West Country ieCornwall / Devon / Somerset which is where the village of Widdicombe was situated - this suggests a fair chunk of Celtic blood since the recent BBC mass DNA survey indicated the southern English are 50/75% Celtic anyhow and much more so further West
4 My own researches which are so far only back to 1880 all give trails which go back to the West country and very few links in the North of England ..
