Thank you, the link had been provided, but:
There is no doubt that Patrick is the child of his parents, so uncertain parent of Patrick is not accurate.
That the unknown male MAY be the child of Patrick is already marked as uncertain and not the issue.
The main issue is I believe, how to resolve the unmerged match of Patrick and Peter to reunite the families with wife Mary Buchanan.
(The downstream duplicated children have been agreed and merged back together again, albeit currently as children of Peter and Mary, not of Patrick and the same Mary)
