almost certainly the correct identification for Jane - in 1861 Robt is a widower - a tailor in Strand street (no number given) - dau Jane is a National School teacher (ie one who is qualified to teach in a 'national' (= Lancastrian type) school - this corresponds to 1863 directory entry for Jane at St Barnabas infants school + her home address given as 19 Strand street. (prob got job post 1857 as a Sarah Brown was there in 1857)
Can't immediately see a bur in period 1851 to 1861 for Eleanor Gell/Gale however
