This could be the same Margaret in 1871 and her birthplace is now Manchester:
1871 census on ancestry
52 Egan St, Preston
Joseph Tipping Head Mar 35 Plasterer Lancashire Goosnargh
Elizabeth Do Wife Do 35 Do Hindley
John Do Son 10 Scholar Do Wigan
James Do Do 7 Do Do Preston
Margaret Wilson Lodger Widow 38 Cotton Weaver Do Manchester
Alice Do Daur Unm 18 Do Do Do Preston
Catherine Do " 9 Scholar Gibralter
Catherine's birthplace would explain why I can't find the Wilsons in 1861!
Alice Wilson, age 19, weaver, daughter of late Samuel Wilson, spinner, marries a William Sumner 5 Oct 1872 in Preston, according to Lancashire OPC, so it looks like the right family.
