Dock Keen

Dock Keen is listed on Ellen Keen Haley death's paper. Ellen came from Mississippi, and may have been married twice. First, to a Marshall, and then to William Sam Haley. I am trying to find out about Dock Keen. How many kids did he and his wife have, were they
Indians, where was the family from, and other information. I am looking for family Bibles, pictures, and other paperwork that would
help in my research. My grandmother Wyatt talked about being "Black
Dutch", and seemed happy to say it. I did not really asked about it
like I should have, and now I am sorry that I did not.
