I have a copy of the Downen Family Tree. I just sent it off to the printer to have a copy made. I believe it is the most accurate record that we have up to about 1960, but it has not been updated much since then. We really need to get together to work on the newer persons before the data is lost. I would be happy to furnish you with a copy as soon as my copy comes back. I am going to make copies available for "the Downen Nation" which is a Downen networking group on facebook that is open to all Downen and relations. I am not sure, but I think that the book is about 50 pages and starts about 1740 with Josiah Downing.
