Searching on these names, You'll find their ancestors.
As far as I know they had 6 other children, but maybe I missed one or two, because of the privacy-laws.
Thankyou for replying. I am trying to find out who Petronella married (second marriage), she married my father in 1947 in Glasgow Scotland but it was annulled/divorced) and whether she has any children or has passed away.
These are data which will be difficult to find, because of privacy .
Did You put Your question on the Dutch forum also ? If not, I would try it.
