It is over 13 years since I created this profile. Actually reviewing the revisions, it appears that a number of different profiles have been merged. So I am unsure now without investigation what information I input and what has been added by others. I would need to go back to a copy of McKensie or the family tree to check.
Children born after the father is 65 isn't impossible despite being illadvised and unlikely. I understand your skepticism. But obviously born before his father is an obvious mistake.
Many Thanks,
Roderick Brown
