Looking for Walker and Taylor and Holiday Conection Proof

Here is how I go back. Me-My Grandfather Joseph Alex Walker-GGrandfather William David Walker-GGGrandfather Alex (Wilson) Walker-GGGGrandfather David Wood Walker-GGGGGrandfather David Wood Walker SR.
Alex Wilson Walker Married Lavinia Taylor. Lavinia's parents were William Taylor and Rebecca Hilton. William Taylor's parents were William Taylor # 1 and Sally Holiday. Sally Holiday's parents were Annie V. Lewellyn(Choctaw Indain)and John Holliday?
There is Creek and Choctaw Indian. The Creek goes back to the Wind Clan. A lot of this information is around Simpson County, Mississippi but some moved to Texas. David Wood Walker was born in the Choctaw Reservision Mississippi. I think David Wood Walker SR. may have been from Georgia.
