Joseph and Ruhamah (Rockwell) Hawkins had seven children recorded at Norwalk. It is possible there were others, born after their move out of town. By 1820, Ruhamah Hawkins was enumerated in the census as the head of a household back in Wilton. Last record of her husband Joseph was a sale of Wilton land on 30 April 1817, in which he gave his residence as Redding. Among the children was John Wesley Hawkins, born 29 March 1798. He is probably the John W. Hawkins who, with wife Polly, appears in the Ridgefield land records in the 1820s. Neil Hawkins informs me that he has a copy of the death certificate of his ancestor John Rockwell Hawkins of Orange Co., NY. It identifies JRH's birthplace as Ridgefield and his father as John Wesley Hawkins--no doubt the son of Joseph and Ruhamah (Rockwell) Hawkins.
Brian Logan, a Rockwell descendant from a different branch of the John line, generously took the time to photograph some Rockwell sites in Wilton. Here is a digital photo of John Rockwell Sr's grave at Comstock Hill, including the Revolutionary War marker that should have gone to his son's grave in Otsego, New York.
