Frederick Van Cortlandt, the oldest son, was born in 1698, and married Francina, daughter of Augustus Jay (the ancestor of the family bearing that famous name) and Anna Maria Bayard, his wife. The old family Bible, printed in Amsterdam in 1714, and now in possession of Augustus Van Cortlandt, ofYonkers, contains the following record of this family, written in Dutch by Francina Van Cortlandt, which is of much interest as a relic of the times when that language was in general use throughout the county :

" Niew York, den 19 January 172i, ben Ick francina Jay met frederick Van Cortlandt soon van Jacobus Van Cortlandt, in den howelicke staet beve stight, door Dominie Antonidus."
