Re: Brown, / Alabama / Native American
In 1848 Knox county Tx did not exist.There was no population in Knox county until after 1870 due to Indian raids.I found your Sydney H. Brown on the Marengo co Al 1900 census there he says his birth was Aug 1847 and he was born in NC. They had been married 21 years she had given birth to 9 children 8 living, seven were in the household. Two of their listed children were born in TX Herman 16 years old born Oct 1883 TX and Sallie K. 13 born Aug 1886 TX.Which suggests they came to TX but found it not to their liking.
I hope this helps.
