This woman was a daughter of Claas De Graaf and Elisabeth Brouwer. She probably was born in Albany, New York, where two children of the same family were baptized in 1691 and 1693. Church records for her identify her as Maria or variants of that name, but Schenectady histories by Pearson (1873) and Yates (1902) give her name as Margaret, Margarita, or Margriet.
Maria de Graaf married Robert Yates in Schenectady on 13 February 1712. Betty Fink's transcription of Schenectady marriage records shows the marriage on 13 February 1712 of Robbert Jest and Maria De Graaft. The record transcription published in the New York Genealogical and Biographical Record in 1942 reports the marriage on 13 February 1712 of Rebbert Yeat and Maria de Graaf.
