In December 1685, she was identified as twenty-three-years-old and an heir in the will of her then deceased parents.

On December 9, 1685, she marrried Anthony Barentse Bradt. By 1708, their eleven children had been baptized at the Albany Dutch church where she was a member.

In 1725, Lutheran church records referred to her slave "Betty."
