There are apparently two entries concerning the marriage of Robert Lovelock: 15 October 1815 and 23 October 1815. In the first his wife's name is given as Jane TOYE, whereas in the second it is Jane SAYE.
Much more importantly the 15 Oct entry records that Robert is a widower of Eaton (sic) Wiltshire, and a member of the Royal Veteran Battalion.
Jane may have remarried to James MEDLIN in Budock on 19 Dec 1830
