I can help with the origin of Langille's to Canada....Alexander was not one of the immigrants. in 1752, 2 ships , the Betty and the Sally carried a few of the Langille family from their home in Montbeliard, France (was of German occupation then) to Halifax, then on to Lunenburg, N.S. Leopold Frederick Langille(1728) on the Betty, stayed in Lunenburg, and is the head of the "South Shore" Langille's David Langille(1715), his son Jean-Jacques(1736), and stepson Jacques(1743), were all on the ship Sally, and moved from Lunenburg to River John about 1771. Mathias Langille(Matthew), David's brother, was on the ship Betty. Decendants of Mathieu and his brother David,son Jean-Jacques, and stepson Jacques, have become known as the"North Shore" Langille's Al Fletcher has a good siteon the history and genealogy of the Langille's:Montbeliard.org , as well as Karen Fletcher's site of Langille's :www.freepages.genealogy.rootsweb.com/~Langille.Christoph Langille (1797) is married to Catherine Mattatall (1803)in Al Fletchers genealogy page. check it out. There are a few more good ones around if you search. If I can be of further help...just ask, Bob Langill, Montreal,Canada, eh! father of James Langill, brother of William James Langill, son of William James Langill, g.son of S.James Langill, gg.son of James William Langill, gggson of James Wadell Langill.
