Vermillion Family Genealogy Forum
In response to your query on Giles Vermillion
whom many if not all of us seem to descend from. My father has two books of Vermillion geneaology (perhaps the Vermillion I and II referred to in another query at this site)which indicate that Gilles came from Wales, but his wife was from Scotland. It is my understanding that many french protestants came to Wales after the St. Bartholemew's day massacre, but there is something like a hundred year gap between the two events. Anecdotally, there are many Vermillions in Louisiana who are descended from the Acadians who were forcibly removed after France lost the French and Indian War. These people were predominantly Protestant so there could be some connection there as well.
Hope this is helpful.
