Don't let the spelling of a name hinder your research. I have a Campbell I'm researching...I check Cammel, Cambpell, Kimble, Gamble...etc. Good ol' Ellis Campbell...used Cammel on land records...but they were done by a neighbor. He died and another neighbor put Elias Campbell...who knows. We check them all.
Yes, takes longer...but we know some way back then were not very good spellers...and some didn't read or write at all.
