I am trying to find a record of death for George Cattle born c 1776 Barton on Humber. His wife was Nancy Cattle who can be found as a widow in the 1841 census living at Cumberland Street, Sculcoates. She died in 1859 aged 80, with her obituary referring to her “ late husband George Cattle, mariner, of this town (Hull)” . I presume George died before 1839 when official records began ,any ideas where I might look?
