J. Loomans, Johannes, born Hazerswoude 04-12-1904, married Hazerswoude 01-08-1930 with Maria van der Meer, born 28-10-1903, died Leiden 21-12-1996.
Johannes father Willem Loomans, born 15-12-1873, died 18-03-1966, (married to Petronella Anna Opdam) was a half brother of my grandfather
I med them a couple of times in the fiftees.
if You are interrested I have some pictures of Willem and Petronella as wel as from Johannes and Maria.
excuse my English, I lost it over the years, iIm 80 years now.
I started to try find out the family tree of the Loomans in 1995, and I complete it in 2005, so Johannes must be dead by now.
if You wanna know more, feel free to ask.
