    I would like to express my deepest thanks to Doreen Powers, [email protected], who generously shared this piece of family history without my asking. I had contacted her about a Wynkoop family slave obituary earlier and in the course of a couple of emails she happened to mention this small Wynkoop family genealogy which was completely unknown to me at the time. She very generously sent me a scan of it, although she wasn't quite sure of the name of the source. It took several hours of research in library catalogs across the United States before we were sure that we had tracked down the right title.

    Doreen, thank you so very much. I hope you have as much success in your family search as I've had in mine.

    All my best,

    Chris
