Hi
The problem is, there are two Mary Ann Doyles, but there seems to be a difference of opinion on here as to which one is yours.
Your lady married Mr Mower and then later married Joseph Jones. Second marriage at St Paul Deptford, 9 October 1890, as Mary Ann Muir, a widow. Age 33, father James Doyle, deceased.
I am concurring with avm228.
We can absolutely eliminate the one born in Lavender Place in 1855, it is not your Mary, her father was John, she had illegitimate children but not the ones you are interested in. She is the one removed from Shoreditch.
The second Mary is living in Lavender Place in 1881. That is your lady, and she is very likely to be the Mary Ann Doyle who was baptised in August 1858, St George in the East, parents James and Ann, as again detailed by avm228.
Do you have Mary in 1891? Who were the children with her?
John
