Am trying to find others researching William Perky who marr. Frances Spoon Aug. 20, 1849 in Grainger Co. Tn. They were on the 1850 Grngr. Co. census as Perkapile but I have not been able to locate them again. Their children in 1850 were Margaret 9, Cornelia 6, Susan 3 and John A. 8/12. Where did they go?
