St. Andre is not a common name. My father was Richard St. Andre. My grandfather was Henry St. Andre. My grandmother mother was Ida Benoit. My family line comes from the Worcester MA area. I have found that there is a line of St. Andres in New England, Louisiana and in the upper midwest... those seem to be the starting points - now I have found St. Andres in many states. I have encountered a few that I believe can be traced back into my family tree. Canada seems to have many St. Andres. I have heard before of a possible soldier connection with how St Andres arrived in the New World.
