Dear Brent, I am Frank Crothers of New Orleans. I have in my family tree an Isabella Crothers, the daughter of Samuel Crothers and Mary McChord. Samuel was a Presbyterian minister in Greenfield, Ohio for fifty years. My gggggrfather, Benjamin, was his brother. The McChords came from Baltimore. This Isabella had eleven children. Don't know if this is the one you're looking for. Hope this helps.
