Can I get help with the Dunwoody Family?

Question

I am stuck trying to locate the correct documents for the Dunwoody family either from Tennessee or Texas

I would like to determine, too, if there are indigenous roots. 

John Dunwoody:https://www.wikitree.com/wiki/Dunwoody-236

His wife (?): Susan or Susannah Bird. She is possibly from the Cherokee Tribe in Texas https://www.wikitree.com/wiki/Bird-3130

Daughter: Martha Dunwoody https://www.wikitree.com/wiki/Dunwoody-234 

Answer 1

According to a book digitized at Ancestry called "The Ancestry and Posterity of Matthew, John, Daniel, and Samuel Lyle, Pioneer Settlers in Virginia," John and Susan were married in 1852; they were the parents of David and Martha.  By 1860 the family was in Texas and David, listed as an orphan, was living with his uncle David and his family while Martha was living with a couple named Featherston.  This suggests that both their parents had died before 1860.  I don't see anything to suggest that Susan Bird had any Cherokee connection; there is no Cherokee "Bird" family in either Tennessee or Texas in 1850.  

There was apparently a Dunwoody family Bible belonging to Patrick Dunwoody which went to Texas with son David and remained there. It might have a clue if you can locate it.  See article in the Fort Worth Star-Telegram, 1936 https://www.newspapers.com/article/fort-worth-star-telegram-family-bible/143277686/
