My good friend the late Dennis Cain had ancestors who settled first in Canada then Michigan. This may be another branch of your family. There is an easy way to find out. Dennis and I are DNA matches so if you have had a Y-DNA test and match us then I or Dennis' widow could try to match family trees. We used the Cain DNA project at www.familytreedna.com/public/Cain-Caine for our tests.
