Reply #26. I've been trying to untangle Joseph & Mary & offspring too.
The word "spinster" next to Mary Gale's name was for her daughter, Mary Jane Vickers' baptism not for Mary Gale's burial. (Transcription on Lancashire OPC; I haven't seen original.) Burial register states her age, occupation (washerwoman) and address she died at; marital status not recorded.
If Mary Jane Vickers Gale was a baby when she was baptised in 1859 she couldn't have been Joseph's daughter. If she wasn't a baby and she was old enough to have been his daughter, why was Joseph not recorded as father in baptism entry? (There was a similar situation with my ancestors in 1858.)
I had no luck either with finding a birth registration for our Mary Jane Gale. There was a birth registration for Mary A. Gale, mother's maiden name Austin 1859 Bolton. Can rule her out. Burial at Tonge cemetery July same year of Mary Ann Gale, aged 10 days, daughter of John & Ann; place of death Back King St., Bolton. Marriage 1859, Bolton St. Peter, John Gale & Hannah Austin. Info from Lancs. BMD and Lancashire Online Parish Clerks. I can't find any other likely Mary Gale birth registrations on Lancs. BMD and I looked a few years before 1859. I've been having trouble with GRO so couldn't find births there.
Joseph Gale's occupation at Elizabeth's baptism 1850 was coachman and cab driver at his burial, basically the same type of work.
Doesn't seem to be a birth registration for Elizabeth Gale either. However there is one for Elizabeth COURT 1850 Little Bolton, mother's maiden name Court. Possible confusion between Gort, Cort and Court?

Marriage of Joseph Gale and Mary Cort/Gort was at Christ Church, Bolton. There were several churches called Christ Church in the Greater Bolton area. Marriage not on LANOPC so no other information about them.
I've tried searching for our Mary's birth registration under surnames Court and Gort but no joy.
There was an older Joseph Gale in Bolton who caught my interest, possibly more than one. One was an ostler or groom. He had a wife Elizabeth and 2 sons, Francis, baptised 1830 and William bap. 1834 at St. Peter, Bolton. 2 sons named Cornelius were born to Joseph Gale 1837 & 1841. They died as infants. Joseph was bookkeeper at 1st and a brewer at 2nd. Francis married 1854.
