Hi Mark
There is a family tree for this line on Ancestry. If you have a subscription/can access, see
www.ancestry.co.uk/family-tree/person/tree/104267042/person/340063124958/factsThey have Ann Mary Murphy's parents as Michael and Mary Toole. I was trying to link you to the birth on
www.irishgenealogy.ie/en/ but there seems to be some access problems at present.
Birth here
www.familysearch.org/ark:/61903/1:1:QGYW-2BFYThe details given for her RC baptism from the index:
Anne Muprhy
Birth Date: 21 Jan 1877
Baptism Date: 23 Jan 1877
Baptism Place: Tullow, Carlow, Ireland
Father: Michl Murphy
Mother: Mary Tool
Have you been able to search for her on the 1939 Register to see what shows for her birth date?
Her age at death in 1945, aged 68, would fit with a 1877 birth year.
