I am not researching the family you mentioned, but if you have questions about this family, I might be able to help you. My family (surname Kan) lived in the Zaan area for 300 years and I often visit the Zaanstad archives in Koog aan de Zaan.
Antjes surname was was 'Bethlem' in stead of 'Bethlam'. Go to www.genlias.nl
(choose the English version and you will find her marriage with Klaas.
I was born in Krommenie, which is a village north of Wormerveer and the familynames you mentioned sound very familiar to me.
