John died in 1885 aged 45, and Mary Jane Hillman remarried the same year to Edmund William Brooking (29 Nov 1885 at Upton - both residing at 20 Union St).
Mary Jane claimed to be 35 at remarriage in 1885, having been 36 in 1881

Perhaps age was a sensitive subject - Edmund (a traveller) was only "28" in 1885.
Her father: James Lock, carrier.
Edmund's father: James Frederick Brooking, miner.
