I have been working hard the last year on my family genealogy. I have a link to the Dall family. My maternal great-grandfather was William M. Dall. My grandmother Grace was his daughter from his second marriage to Grace /Lansing/. I have information on the line from there as well as some information going backwards. I may even have some pictures of Charles Moses Dall in my Grandmothers old photos. I've been going through and there are quite a few Dall's.
