I don't see her baptism record, though multiple sources say she was baptized on 25 Jan 1671. Her older brother was baptized with the family name of Kip though. And
* 1697 11 Jul Johannes Ryckman, j.m. Van N. Albanien, Catarina Kip, j.d. Van N. Yorck, d' Eerste woonende tot N. Albanie, en twede alhier.
So Kip is fine.
