It has been a long time since you posted this message but I'm going to reply and hope that you are still online. My great grandfather Abel was a brother to your Henrietta. My grandfather J. Nyhof Poel did quite a bit of research with Henry Beets back in the 1960's. My grandfather was also in possession of quite a few old picture "postcards" that had belonged to his Uncle Herm, who was Henrietta's brother. Several of these were of Henrietta's daughters, including Elsie, Jennie, and Josie. If you are still interested in exchanging information, please reply.
