Ah... I now see another problem. When I attached Ann as John's mother, I got a warning message that she would have been 55 years of age-- rather old to be a mother.
So either something is wrong with John's birth record about the identity of his mother, or Nicholas had a second, younger wife by the same name, Ann. Or Ann Long-351's birth date is inaccurate.
That is probably why Ann was detached as other of John.
