I have William Darwent b Birmingham abt 1808 m to Selina Taylor b abt 1817 the marriage probably before 1837 as I can't find it on FreeBMD by any spelling. They were probably married in London as they have children born there 1838,40 and 44. By 1851 Census they were in Sheffield but Selina had died there before that. Now of course what I needed was the 1841 census but that for St Lukes where they were is one of the missing ones. I know nothing of Selina bar her name. Any bright ideas please?
