Thomas Maisey married Sabina Snell in 1860 and had Eliza (1861), Robert (1863) and Matilda (1867). By 1881 Thomas is with Eliza Morton and has more children. Sabina has disappeared.
On the 1861 census Thomas and 2 of his brothers, James and John, are living in Bham. All are in the fishmonger trade.
Also in Bham is Ann Kilmartin, the illegitimate daughter of James' wife, Eliza Bassingthwaite, whose husband is also in the fishmonger trade. I think she was reg. and baptised as Georgiana.
Finally in 1861 there are a John and Hannah Loodmer, both born Norfolk, in Bham, whilst with Robert and Margaret back in Great Yarmouth is a William Loodger.
