I am looking for any information on the family and descendents of Margarietje Polhemus b. 1704 married to Derick Ammerman b. 1707. Also am inquiring if the name Derick could also be Hendrick. I have 5 children for them in my files:Derick, Daniel, Jan, Sarah, and Cornelius. Is there any more and does anyone know birth dates? I am looking for a possible daughter born about 1744 with the name of "Enni"--which could be shortened version of another name.
