I heard back from Mary Taylor this morning.
This is her reply
Angelina appears to have been born when her mother, Mary Ann, was just 18,
and a single parent, and brought up alongside her aunts and uncles in her
grandparents house.
It would be very unusual in these circumstances for there to be anything
in writing anywhere about her father. If Mary Ann's parents had disowned
her, and she had had Angelina in the Workhouse, there may have been
affiliation proceedings, as the Workhouse tried to recover some of the
costs of looking after mother and baby, but apart from that there is
rarely any paperwork. She clearly didn't have the baby in the Workhouse,
as there is no birth certificate.
It is also unlikely that Mary Ann's later partner, John Maycock, is the
father of the baby. The father will have been either unable to marry Mary
Ann at the time of Angelina's birth, or no-one knew who he was but Mary
Ann, and she wasn't telling! Either way, it is very unlikely that she
later married the father - he would have been associated with a very
unhappy time of her life
Just thought I'd let you all know.
Thanks for all your help
