Or his father... He was married before. 

Very possible.  Maybe you can help me locate him through this search tool?

Thanks.

no such luck :(

Thanks for trying.

I think that this is the first marriage of Daem (who married in 1674 with Gijsbertje Jans):

Source: open archieven.

Marriage on 31-07-1671 at Leiden:

Daem Daemsz, born Amersfoort, now Santstraet Leiden x

Heyltge Jans Coorevaer, born Gouda.

Witness for Daem is Harmen Hendricx, acquaintance.

I think Heyltge and Oetje are the same person.

If i'm right Daem Daemsz is a brother of Jan Daemsz and not his father

Amersfoort:

Baptise of Adam Daemsen 11-09-1676 son of Adam Daemsen and Gisberte Jans. Witness is Basilia Bartholumis. 

Church: OudKatholieke Clerezij.
