You might find evidence of their arrival in Canada, but there's 3000 miles of border between Canada and the US and only in the past few years have they thought much about tightening it up. There have always been a million places you could just walk across, through the woods or across a frozen river, or go by boat..

I'd think your family oral history would be the most likely place to find where they crossed--cause there wouldn't be an official record, would there?

Thanks for those links gnu.
