Samuel and Sarah (Polson) Rorex

Looking for ancestors of Samuel 'Sam' Rorex and Sarah Polson/Palson or lines of any cousins who descend from this couple.The Rorex family lived in Jackson Co., AL.I think the surname may have originally been spelled Roach and may have changed from Roach to Rorex with Samuel, in which case he had a brother named John B(reckenridge?) Roach, both living in Dist. 19, Chambers Co., AL in 1850.
