1819 James Lyon-Electious Hays
1820 Michael Lyon -James Lyon

These deeds connect James Lyon b. 1768 in Maryland to his two sons Michael and Thomas.
Electious Hays son Isaac, would marry Orpha Lyon daughter of James Lyon.
Tradition at the time was the first son born was named after the fathers's father. That would make James Lyon's father Michael Lyon since his oldest son was named Michael.
