My great-grandfather John Edward McMullen was a tailor on Conran Street, Manchester and in Manchester city centre, late 1800s to 1940s. His wife Jemima was a furrier and they lived in Back Irk Street. In later years the shops were taken over by his sons.
I am looking for any information on his father William McMullen born 1844 in Ireland. John Edward was apprenticed to his father on 1881 census. What happened to him?
