The Massachusetts death index has a Hannah Maher who died in Boston in 1930. No maiden name is shown on the index, so Maher would seem to be her maiden name. Not sure if she's yours, but maybe.
According to cemetery records, the owner of the plot where Hannah was buried was an Ernest Dixey.

https://www.familysearch.org/ark:/61903/1:1:KBZB-YR3Her parents are listed as William Maher & Anna Pittman, which differs from the parents given for Hannah & Mary. Are they related?
This is interesting. Catherine Dixey, who died in 1917 was buried beside Hannah in Oct. 1930. Hannah was buried in June 1930. Was Catherine moved from her previous burial spot in 1917, so she could lay beside Hannah, thus moved in Oct 1930. Catherine's death record states she was buried at New Calvary Cemetery in Feb. 1917.
