Saw your Considine posting so checked for the Davoren's. Patrick didn't get to Boston until Jun 1850 at age 16. Catherine was already here landing in 1849 at age 19. They had a total of 6 children (1900 census). I have a copy of the Calvery Cemetery internment as Genevieve was the last buried there and my father the eldest son.
I thought Patrick had bought the plot as Elizabeth Shannon was so ill and was the first buried. I thought the other 3 died in Mass. Patrick did have a younger brother/cousin living in the area at the time (Chicago).
