Joy, would you have any additional info on Vernal after 1880? Do you kjnow if he died in TN and were Lucinda and Nancy married there. I found a Benjamin Kizer in Purdy, McNairy Co in 1870 age 21. could be Benjamin son of Venral. A descendent of Nicholas lives in Lexington,Tn and has posted on this site previously.
If you want we can discuss this family and try to determine some origination marriages. There seems to be a migration from Pa MD in the 1790 to TN. I have another family that shows up in Davidson Co mid 1790 and census records say they are from MD.
