Lynne
She had her first child in 1834 according to IGI. Looks like Jane remarried a George GADDARN West Derby Dec 1861 8b 643. Lancashire BMD also gives her maiden name as Fell so know this was the same Jane. Looking at Free BMD George died March Qtr 1875 aged 57 and Jane March Qtr 1886 but age given as 65 (looks like a few years shaved..maybe because a younger husband!...or there are instances when there was no one who knew the exact age of the person who died).
Maybe someone who has access to say 1871 Census could look the couple up for you? Cant find her in 1881 as name likely to be mis transcribed?
