I created an unmerged match to create a connection, not to block a merge.
My message [PS now deleted] was only trying to say there's a missing generation in the Visitation book.
According to Ormerod, Piers had 3 sons by his wife, and 3 daughters, and 3 more of each who weren't hers, though we aren't told whether she was his wife at the time.
Actually this might explain why the Visitation pedigree drew a discreet veil over that generation.
But it's dangerous to quote Ormerod without consulting Helsby's "2nd edition".
