Finally located the death record for Eiske Jacobs Dam. Took a little due diligence to find. I knew from Egbert Jacobs' death certificate that Eiske had died prior to 1847, and from Sybold Jacobs' death certificate, dated 1833, that Eiske was still alive. This gave me the range 1833-1847.
I also knew Eiske's last known residence at no. 95 in Stedum. Below is her death record.
On the 1813 wedding registration of Jacob Jacobs, we find the name of Jacob Cornelis Kruize. Normally, since Jacob died in 1822, we find him listed as "overleden" or deceased. In this instance, Jacob is listed as being present - as is his wife Eiske Jacobs Dam. On the document Eiske's signature is given but not Jacob's. Sadly, it appears that Jacob was unable to write his name. This would have been a great piece of Kruizenga history. But we do have quite a collection of family members in addition to the mother: elder brother Hindrik Jacobs and uncles (mother's side) Egbert and Derk Dam.
