Richardson Family: Georgia,S & N. Carolina, Tennessee, Arkansas

I am new to this Genealogy Wise Group, But Have been researching forover 20 years. My dead in Family line is my Richardson line, of whitch Is my Fathers line.  Last know ancestor is Samuel K. Richardson, born 1806 inGeorgia, unknown County. He had a brother name Thomas L.Richardson born 1808 in Georgia and a sister Mary Ann Richardson born 1819 in Georgia.

Samuel and his brother stayed close during there lives living in both Georgia and Tennessee, later (1850) moving to Arkansas. Census records of both brothers show the parents born in N.C. or S.C, Samuel married twice having children by both marriages. 1st was Jane Hassler of Roane CO. TN. and 2nd was Elizabeth Jane Harvey also of Roane CO. TN.  Thomas married Frances Cates.  Any help in connecting this Richardson to their ancestors would be greatly appreciated. My feeling tell me they are some how connected to the Richardsons of the New England states. I have lots of data from Samuel forward, present day.
