Descendants of Enoch Howard Rial, Lee County Mississippi

Enoch Howard Rial appears on a Land Patent 10 December 1840 in Bolivar County Mississippi. I do not know of Enoch's history before Mississippi. Later in the 1850 and 1860 Census he is listed in Itawamba County (Priceville). In 1866 this part of Itawamba County became Lee County. Priceville is today in Tupelo Mississippi. The Census information shows Enoch's birthplace as North Carolina and his wife Mary's birthplace as SC. Their oldest daughter Mary Howard Rial's birthplace is Al, and the rest of the children were born in Mississippi. I am seeking to find Enoch's birth family. He is calculated to have been born about 1814.
