I must admit that I am not familiar with any one named Femmetje
Hendricks, although I am related to a Margaret Hendricks, the wife of
Matthys Jansen and later Thomas Chambers. She and Matthys were in Harlem
by 1646, and Matthys died in Esopus (Kingston) before 1656 or 1663.
Some books you may want to check out are:

You might also want to check out, if you can find it, 'The Baptismal and
Marriage Registers of Kingston, NY's Old Dutch Church' by Roswell R. Hoes
