Johannes Pieterse Quackenbosch currently has 43 siblings and 18 children and 2 wives.
The wives are duplicates.
I haven't looked at the siblings yet but 43 is an unbelievable number.
The children are a problem. DOBs range from the 1640s to the 1690s, apart from a 60 year span on children being very suspect given that Johannes is born c.1642 his having children in the 1640s is impossible.
Also several of the children have the wrong gender for their name, a sure sign of amateur family historians at work.
