I am having trouble tracing records for Samuel and Elizabeth Harrison. Elizabeth, nee Smith, is shown in census records as being born in Woodchester in about 1811. She had four children, all living with her in Cheltenham in 1851 - no sign of Samuel, although she is shown as wife not widow. By 1859 she had moved to London where her daughters married, she was a widow in 1861. But I can't find Samuel on the 1841 or 1851 censuses. I would appreciate advice on where I can find a record of their marriage, their birth records, and the birth of their eldest daughter (also Elizabeth) - in Cheltenham - in 1833?
