A Moses PRAGNELL [sic] married a Sarah COOPER in West Dean on 7 Aug 1794, both of this parish, and a Sarah PRAGNELL daughter of Moses and Sarah née COOPER was baptised there on 29 Jun 1795, aged 3 days. West Dean is immediately over the Wiltshire border, about 2 miles from Lockerley and 5 miles from Michelmersh. I can't find any record of other children of Moses and Sarah in West Dean. This may be explained by a Moses PRANGNEL [sic] who was buried in Whiteparish on 18 Jan 1795. If so, Sarah was his posthumous child, but there was more than one Moses PRAGNELL and it seems more likely that the man who died was someone else. Back in Hampshire, a Moses and Sarah have ten children baptised in West Tytherley between 1798 and 1823. I'm inclined to believe this is the couple who married in West Dean as the dates fit and I can't find a suitable baptism in Hampshire. They appear on the 1841 census for West Tytherley, both aged 65-69. There are burials there for a Moses on 9 Nov 1844, aged 73 (so born 1770-71) and a Sarah on 5 Feb 1848, aged 75 (so born 1772-73). I suspect Moses is the son of John PAGNELL baptised in West Tytherley on 10 Jan 1773. Possibly your Moses is the eldest son of this Moses and Sarah, as it's slightly unusual for there not to be a son named after the father, and the dates fit reasonably well. The Sarah who witnessed your Moses's marriage to Hannah WILTON could be either his mother or sister.
