Finding a Sister Through Census Records

Below is the 1799 marriage record for Peggy Warburton and Charles Patefield.

This marriage for Margaret Warburton states she is of Manchester. My notes for her family so far had citations to Prestwich, Lancashire, and referred to her as Peggy. I needed to verify I had the correct person. How did I confirm this was the right Warburton female?

By following Margaret/Peggy Patefield through some of the later census records, I was able to match year and location of birth with Peggy's baptism record.  But the clincher was found in the 1851 census record where at age 74, she is listed as a widow, head of household, with her widowed brother, William Warburton, residing with her.
