A good approach is always to list the names of the children. In this particular case, it could well be that this was not Petrus his first marriage, but that he was previously married to Maria Caes and, before that, with Catharina Ceulmans. Assuming that this is correct, we can expand the list of children with Joannes (1723), Joanna (1725), Franciscus (1728), Catharina (1730), Joanna (1732), and Maria (1734). We can further assume that Petrus was born somewhere between 1690 and 1700, which matches with Petrus, ged. Putte 2.6.1693, son of Petrus Bosmans and Catharina Vertommen, which matches with the name of the child born in 1730. But it is impossible to say things with certainty.
A similar exercise would then follow for Petronella Hendricx, where, given the names of the children she had with Petrus Bosmans, I would not be surprised it this wasn't her first marriage either.
