Anne, Checked out the marriage for Ellen she married John Tomlinson Millington, in 1861 & 71 they were living in West Derby Lancashire. You can check out their children in 1881 ref: RG11/3705 folio 76 page 22 West Derby 115 Oxford Street you the LDS site. John T is there with a new wife Ellen would have died before 1881. Positive it's Ellen Stubbs got a son Frederick Stubbs Millington.
