I found your book at the library, and my husband and I scanned it twice looking for a mention of a Henry Simmons. The book does not have that many pages, so it was fairly easy to do. We only found one mention of a Henry Williams that fits the dates you provided. According to that information, there was a Henry Simmons born Aug. 13, 1811 to a Charles Simmons and Lydia Weston. There was no other mention of Henry after that. We photocopied the page if you would like to see it.
