Do you have any more information on Mary J? My father's sister was Mary Jane Callaghan born 1888 in Consett, County Durham, England. Parents were Thomas Callaghan and Elizabeth Ann (formerly Turner) Callaghan. I have been looking for dad's siblings since 1989.
I hope she is the one you are requiring about. I have some certificates and census back to parent's parents.
Good luck in your research.
