Netherlands - Vos Weinreich (also connection to Spain)

[kiwianna]

Bit lost on this brick wall and wondered if anyone can throw any light on it with fresh eyes.
I'm helping with my partners family tree which  is centered in the Netherlands. Lots of family stories but I'm trying to work with fact.

What I know..
I have a photo of a tombstone in Spain which reads Anna Weinreich Vos. Born 26 Sept 1911. Died 30 June 1978.
This is my partners Grandmother,  she was definitely born in Netherlands and died in Spain. I believe her husband's name was Kareltje Weinreich.  He also died in Spain. They were apparently married in Spain and I'm thinking is not before 1950.
Her 3 children were born to another relationship prior to this marriage and they have the surname Vos ( we have been told Vos was her maiden name and the children were all given that surname) and she was unmarried to their father. I do have his name. I only have a date of birth for 2 of the children.
I am going thru a lot of papers, all in Dutch and I'm in New Zealand so it's a big of a struggle. Her oldest son is near me but the information is limited and a bit confused. I'm hoping I might come across a birth certificate or similar records.
Any ideas on where to start?

A start:

An Anna VOS was born 26 Sep 1911 in Rotterdam. Her parents were Johannes Willem VOS and Jozina Petronella Everdina VERBOOM

In 1932 and 1935 she was listed as a trainee nurse in the population register of Rotterdam, but in May 1935 she moves to IJsselmonde where she is still a trainee nurse. Only a few months later, she’ll move to Schiedam

One more movement:
Shortly after arriving in Schiedam she seems to have had her first child. By late 1936 she has moved to Vlaardinger-Ambacht.

Brilliant:)
One birth is June 1936. I'm not sure if that's the first of the 3 children
