Where do you end up (geographically) if you follow the families of my four grandparents?
Carroll BradishHe came from Buffalo, NY. His father, John Patrick Bradish, was born in India while his father (Joseph Bradish) was stationed there by the British.
So, the Bradish Line ends up in England, mid-19th century.
Anne GuimondMy maternal grandmother was born around Lotbinère (across and upriver from Québec). The Guimonds were one of the premiere settling families of "New France" going back to the early 1600s. Other relations in this line include Hélène des Portes - the first child born in Québec to European parents (so the Canadian equivalent to Virginia Dare).
Probably the most notable Guimond, Louis Guimond, was a builder of the Basilica of St. Anne de Beaupré and supposedly the first recipient of a miraculous cure (rheumatism).
From there, you go to Bretagne in France.
