Most of my ancestors are from Scotland and quite a few 'Vanished'. They turned up in Australia and New Zealand. Leonie was able to add a confirmation of what I thought had happened. A couple broke up and the young son went with mum. When she remarried (3 times!!) the son took the surname of one of the husbands. The lady did not believe in wasting money on divorce . This explained a close DNA link that had me stumped.
