I am very new to this so my info may or may not be of use. Family legend has it that my great-grandfather entered the US via Vermont or New York from Canada. My grandfather's birth certificate says born in "New York". We don't know if it is city (most likely) or state. His name was David Bourdo. His Parents were David Bourdo and Louisa Knott. Somehow he ended up in Michigan. There are many Bourdo's in Michigan--especially around Detroit. Also, I believe there are several in Wisconsin.
