Are you sure Daniel never went to TX?"Republic of Texas: Poll Lists for 1846" compiled by Marion Day Mullins shows:
Foultrel, Danis in Bexar Co.
Spelling as shown in the book.I do know the publicationdoes not show everyone that was there in 1846.
Did Littleberry have a son named John?John shows up in Dallas Co, TX census 1860 and 1870.By 1880 hehas a different wife.The 1860 census shows he and his family all born in TN, but 1870 & 1880 show John was born KY.
The online census index to which I have access does not have an index, yet, for 1830, 40 & 50, so can't check them for you.I see Littleberry is in TN in 1820 & Daniel is in KY in 1820.
