elizabeth landrum and paul talbot of louisa va and graves ky

i am looking for info on elizabeth landrum, who married paul talbot or talbert in louisa va in 1803. she was the daughter of francis landrum and sarah wren. i do not know who paul's parents were. they moved to mayfield, graves county, ky and paul died there in 1830. i know of two children that paul and elizabeth had: paul jr was a deputy sheriff in graves in the 1850 census and lived with his mother, wife and sister in that census. elizabeth landrum talbert's daughter, also named elizabeth, married a wilkinson of va, possibly named joseph, before 1840 and had three sons. i am descended from the oldest son, francis marion wilkinson,born graves 1840, died in ripley, lauderdale co tn 1910. i found a ky divorce record for joseph and elizabeth wilkinson, no date and a death record for elizabeth wilkinson greer, dated jan 1857 in graves and listing her as the daughter of paul and elizabeth talbert. apparently the younger elizabeth remarried to a mr. greer in the early 1850s. she is listed in the household with her mother and brother, with her three sons, in that 1850 census.no idea what became of joseph. any info on this talbert-landrum-wilkinson family of mayfield in graves county would be appreciated.
