Anne
the reason I said if was the same reason (age difference)
as there are more couples called Henry Black and Isabella,I have been looking through some of the family trees on Ancestry to see if any of them fit in,
The Henry Black and spouse Isabella Wilson
children are Janet and John,
Henry Black and spouse Isabella Cumming
children are James, Henry, Isabella, Annie and John,
I can find most of these on family search
I cant see a William born to these two families but as the births only go up to 1875 it is possible
they could have,
I wonder if William fibbed about his age

will keep looking,
