Diane,
My husband is also a descendant of William C. Dennett and Nannie. His mother was Nancy Rhoades Payne, and her mother was Alice Blanche Dennett. We speak weekly with Ann Moore whose father (I believe) was a sibling of Alice. She indicated that you were a cousin and had done extensive research on the Dennett genealogy. I would be very interested if you would be willing to share anything with us.
Thanks so much,
Donnetta Payne
