Greetings, and a warm welcome to Rootschat.
FreeBMD shows a marriage in the Thrapston registration district:
DIXON Elizabeth, Mar qtr 1883 Thrapston vol 3b p261
on same page as Henry Payne BLAND, William MACKNESS, and Emma Mary MAYES.
The 1891 census (found on FamilySearch) has:
RG12/1197/107 p33 Vernon Street, Northampton
BLAND Henry P, head, 31, shoe room man, born Thrapston
BLAND Elizabeth, wife, 30, born Northampton
BLAND Richard P, son, 6, born Northampton
BLAND Elizabeth A Cornwall, daughter, 4, born Northampton
BLAND Maud Cornwall, daughter, 0, born Northampton.
Ages and birthplaces shown on censuses are not always 100% accurate, and enumerators sometimes made errors, so I wouldn't automatically discount this family.
It might be worth tracking the family on later censuses to see if Elizabeth BLAND's details are consistent with your Lizzie.
