Do you know if Tim, perhaps had a brothers Patrick and or Jeremiah?
My GG Grandfather Patrick Ronan had a Patrick Mahony as a witness to his Naturalization in 1856. A Jeremiah lived in the same building as my family in 1870 and it was either 1860 or 1870 a Patrick Clancy lived in the building.
I know it's grasping at straws and vague, but there isn't much other than that I have.
