Hi,
It looks like Sarah Ann may have died and Edward remarried, Farnworth was in the Bolton registration district and I found these,
DeathSarah Ann WINWOOD Jun Q 1840 Bolton v.21 p.111
MarriageEdward WINWOOD Sep Q Bolton v.21 p.91
Mary NUTTALL with same details.
From the IGI,
Edward WINWOOD age:32
MARY NUTTALL age:28
Marriage: 13 SEP 1840 Farnworth With Kearsley, Lancashire
Looking at this family in 1851 HO107/2206 f.290 p.37 still in Farnworth, a 'do' under Lancashire is crossed out and Derbyshire is his POB
Let me know if you need this transcribed

Regards
Daisy
