Chris, I am estimating between 1800 and 1805. According to the 1800 census, Peter is listed as having 1 male under 10 years of age. Jeddediah was born in 1806 and according to Peter's will William was listed 2nd. Children were listed as Thomas, William,Jeddi, Francis and daughters Sally and Gilly. Hope this will be of some help. Gilly was named after his mother-in-law, Gilly Avery.
