7 Aug 1837, James (24), bachelor and spinner, son of Samuel Mather a weaver married Margaret daughter of Joseph Slater (21), both of Kearsley, mother Ann Stockton. Joseph Stickton was a witness.
The GRO records, record the children with MMN is STCOKTON, not SLATER.
Although married to Margaret with a son Henry (6mo), he was not with them in 1841. Instead James was working nearby at Culcheth, Leigh as a farm servant. Margaret (20) was at Janes Square, Leigh with her son Henry (6 months) and her mother Ann Stockton (65).
In 1851, James and Margaret (38 & 31) were in Ancoats, Manchester with Henry (10), Joseph (6) and Elizabeth A (3)
Around 1855, James and Margaret appear to have seperated. Elizabeth stayed with her mother.
In 1861, James Mather (47) and the four children (but not Elizabeth) were living in Sharples.
In 1871, Margaret Mather (Mar, 51) with Elizabeth Alice (22) and James (19) were "boarding" with he older son Henry and his family. Husband James wasn't there.
In 1877, Another James Mather (son of Ellis and Jane) died at 32 Chapel Street, Blackburn aged 63 (so same age). Probate shows his wife was also Margaret. He was a Grocer. He and his wife Margaret (56 & 54) and daughter Jane (17) were in Blackburn in 1871, so this must be another family.
