Mary Gertrude Duffy (née Martin) (1912-01-06 – 1988-05-23) was my first cousin, three times removed, being the daughter of Robert Martin Jr., son of Robert Martin and Catherine Riley, by Catherine Carr. She married Edward Patrick Duffy (1893-12-03 – 1980-02-03) as his second wife.

She is notable to me for at least two reasons:

• She is the informant for the death record of Catherine Riley, which provides the names of the latter’s parents, which was my first clue enabling me to find Catherine’s roots.
• She is buried under the same headstone as Robert and Catherine.^ref

She had two children, Janet Carey (1932–2014) and Harriet Whitcomb (1934–1991?), in addition to step-relations through Edward’s first wife.
