Hi Doris: I believe we are referring to the same person. My data indicates that her birthdate was 29 April, 1781; however, this could be her baptismal date. Her father and her maternal grandmother were first cousins, once removed. Neeltje was born in Rotterdam, Schenectady, New York. To date, I have not determined the names of her children, but would also like to know them. I do have the names of her siblings' children, however. If you would indicate your e-mail address, I would be happy to send you more detailed information on her ancestry. Susanne
