I have very little to go on here, but am hopeful it will sound familiar to someone.
My great grandmother was Mary Keniry from Ireland. She married my g-grandfather, Simon Peter Canty (probably from County Clare - born 1858). They had one son, Martin in November of 1880 in Ireland. Their second child was Catherine born in February 1888 in Massachusetts, then Michael (1890), John (1892), and Simon Peter (1894).
They may have lived in the Chicago, Illinois area for awhile before coming to the Boston area (Medford).
Any help would be greatly appreciated. I can't find them anywhere, but in the 1930 US Census in Medford, Mass. and actually this is referring to Simon's second wife who was also named Mary.
