A friend of my husband's researched my family tree for free! I've been reading it this morning. The overwhelming majority of family names comes from England with Scotland and Ireland next. Wales, France, and Belgium are represented, too. The earliest date I've found, so far, is 1430.
Here's an interesting one: Sir Robert Bell was the Speaker of the House of Commons in the late 1500's. He served during the reign of Elizabeth the 1st. He lived at Beaupre Hall in Norfolk, England. Here is the link: http://lh.matthewbeckett.com/houses/lh_norfolk_beauprehall_info_gallery.html
Unfortunately, Beaupre Hall fell victim to the wrecking ball in 1966 during that tragic period of English history when country houses were being torn down at an astonishing rate.
So, the quest goes on to find a scottish name with a plaid I like. Stuart is one I've found. I've always been a Jacobite sympathizer. Are those kinds of things inheritable, I wonder?
