If you investigated their tree you may find it doesn't stack up and the only lines that have been worked back are the ones which support their theory. Or more likely a founding father with the "right" surname has been worked forward and some forenames discovered which fit. No matter that any number of people by the same surname will have migrated between the two countries in the centuries since.
Distant matches could be real or could be spurious, I wouldn't waste too much time on them if a candidate MRCA can't be found the appropriate number of generations back.
