Am trying to find out any information regarding Margaret Rockwell, born 1819. She later married Thomas McElhone in 1838, and had 7 children; six of whom survived to adulthood.

We have a list of names in our bible, on different pages, but no clue as how they are related.
Mr Gabrial Rockwell- Killed in Revol War. From White Rock, Ulster, NY
Mrs. Mary Rockwell
Mr. Samuel Rockwell
Any help could be greatly appreciated.
