I, too, am a Pentecost from the Union County bunch; but I know nothing of the Nelsons. Although I've not lived in Indiana for many years, I have done a lot of genealogy and have visited the area as part of my quest. I'd love to touch bases and review any possible connection. Pls contact me directly at... email@example.com
Look forward to meeting another relative.
Cordially...Linda Pentecost Drake
