Mary DEAN of a mother MATHER !
DEAN was possibly a typo for DUNN as there seems to be no Dean and Mather marriage in Bolton, and no other birth. However, Mary died aged 4, buried at Salford and name is confirmed as DEAN.
There are two possible Mary Dean's, both in Salford:
a) Mary (2) and Charles (5), children of Mary Dean (34, Widow, born Yorkshire) living at 22 Ford Street.
b) Mary (2) dughter of who had a sister Alice Dean (aged 9 mo, born Woodchurch, Wirral, Mothers Maiden Name TABBERNER).
3) This is not the Mary from Accrington, as she was a twin of Cornelius Dean.
In 1861, Mary Chatterton (43, born Gisburn, Yorkshire) was House Keeper at 73 Silk St, Salford with son Charles H Dean (15, born Seacomb) and several others. Mary Dean (38) had married Thomas Chatterton, a fishmonger, in 1855. She was the daughter of William Dean a farmer
This older Mary Dean does appear to be the mother of Mary Dean that died, aged 4. It is likely therefopr the father was a MATHER as mother Mary is clearly a spinster. Son Charles Henry Dean (born Wallasey, Wirral , 1846, no MMN) must also be illegitimate.
