I have a MICHAEL CROTTY in my late husbands family. He came to America about 1811, he was indentured to a Doctor in Bedford, VA. After his 7yrs. was up he married Miss Dowdy.
He moved to Greenbried Co., WV (VA). He had several children, one was Charles Preston Crotty who married Nancy Eagle of Lancaster, PA. Does any of this fit your family.
Thanks. I have more info on this family if it fits yours.
