Not sure that we are tied to any of your Willey family but I thought since some names are similar and your side came through Tennessee it was worth a shot. I am GGG of Thomas W. Willey born in TN abt 1847 he lived in Dickson and Henderson and Benton County TN. His Father (also Thomas) was born in Pennsylvania around 1801 and died in TN in 1883. His Grandfather was John Willey. Thomas W. wife was Sarah Melinda Brown from TN abt 1851 and they married abt 1866 in Henderson Co, TN. They had 7 children William Franklin Willey (died in oklahoma), James Raymond Willey (died in Mississippi), Thomas M. Willey (died in TN - memphis), Robert Benjamin Willey (my GG grandfather, died in Tipton Co, TN), Ella M Willey (died in Tipton Co, TN), Ernest E. Willey (died in TN - memphis). Alll lived to adulthood.
As you see many are reuse of names that are also in your families so I wonder if there was a tie back at some point.
