Some of the St. Andre and Botquin (the original name) were at Fort Detroit as soldiers and as merchants and farmers.
We know there was a Charles St. Andre and a Joseph Botquin that went there from the Montreal area of Canada.
They were descendents of Pierre dit St. Andre Borquin.
Don' have any information after that as my data explores my direct ancestors after Pierre St. Andre III. Our clans are settled in Michigan, the New England states, Canada,
of course Louisiana, Utah, California and all points from
Canada. The name originated in France and in the 1600s, Pierre dit St. Andre was born. He married Marie Claude Borgouin and they migrated to Canada. They had a son named Pierre St. Andre Botquin and he in turned had a son named Pierre Botquin St. Andre. From there we have become very well established in the Louisiana area and in New England. As I said, also in Michigan.
