Notes:

No marriage record found: surname given in son John's birth record (GRO register) is same as Ezekiel's first wife, for whom no death record has been found, and if it weren't for the large age difference between the 1871 and 1881 censuses, she could be the same woman using a different forename.
In 1891 census with son John and a lodger, Nathaniel Logan; in 1901 and 1911 censuses as Margaret Logan, widow, but again, no marriage record found.

Margaret married Ezekiel Rubottom between 1871 and 1881. Ezekiel (son of Richard Rubottom and Nancy Gorst) was born on 15 Mar 1826 in Witton cum Twambrooks; died about Feb 1883 in Toxteth Park, Liverpool. [Group Sheet] [Family Chart]
