The Dover, Bogle, McTigret, Crook, Branch, Adams Research

I have assembled approximately 450 names through 8 generations beginning in the late 1700's. On my mother's side (Bogle), we start from her mother's side which are the Branch's who married into the Adams' of Northern Virginia. One ancestor was a Younger. From the Bogle side they stem from S.C. and Georgia to Tennessee to Arkansas to Oklahoma.On my father's side (Dover), we start from the Dover side which starts in N.C. and Ga. through Tennessee, Arkansas, Oklahoma. From his mother's side, McTigret's also originated in the east coast southern states and ended up in Oklahoma. Very little is known on the mother of his mother whose name is Martha/Marsha Crook, a full blood Cherokee Indian in Oklahoma.Would love to hear from anyone that may link our family to our earlier ancestors.
