According to the Weatherby - Kurtz - Sittler Genealogy Lines database at rootsweb.com, Aaron Crim and Lydia Harrow of Pedricktown,Salem County, New Jersey, had four children:
Samuel Crim b: 6 FEB 1820
Sara Crim b: 21 NOV 1822
Isaac Crim b: 28 NOV 1825
Peter Crim b: 22 JAN 1830 in Pedricktown, Salem, NJ
I have traced part of my wife's family back to a Samuel Crimm living in East Boston, Mass., in the 1860's. His approximate birth date, location, and father's name all match this Samuel in New Jersey.
