Coffey to Daniel Boone
The connection between Elizabeth Coffey (married to Francis Behm) of Maries County, Missouri to Daniel Boone is based primarily on the following two publications:

Hazel Atterbury Spraker, The Boone Family - A Genealogical History of the Descendents of George and Mary Boone who came to America in 1717 (1993 reprint by Genealogical Publishing Company) (Rutland, Vermont: Tuttle Company, 1922)

Alice H. Boone, Descendants of Israel Boone, The Boone Family (Israel Boone 1726 - 1756) (Springfield, Missouri: Alice H. Boone, 1969)

The Alice Boone book contains the connections from the Coffeys of Maries County, Missouri to Daniel Boone. I haven't verified this connection.

Boone to Sir James Morgan
There is much controversy amoung researchers on the validity of the connection in the Morgan family to Sir James Morgan, 4th Baronet of Llantarnum. Sarah Morgan was married to Squire Boone, many researchers claim her grandfather was Sir James. This has not been proven but I have included it for reference. This connection should be used with caution. If anyone knows of a definitive research on this connection, we would be interested in hearing about it.
