Hi, it sure looks like we have some kind of connection with the Teirney line.But, I have very little info to research for you.
Maybe you can glean something from what I've gathered on Nora Teirney...
Marriage Record November 3, 1914 in Norwood, MA Vernon H. Cameron, b.PEI, Canada, age 25, paper maker, father Alfred E. Cameron, mother Florence Clay Nora Treasa Tiarnay, b.Ireland, age 27, waitress, father John Tiarnay, mother Nora Geoghegn M.J. Buckley, officiant

1925 Boston Directory Mrs. Nora T. Cameron 54 Thorndike, Roxbury, MA
This along with the info in my first post is all I have on the Tierney family.
I hope this is helpful to you.
Interested in any additional info you may find.
I'm curious about Vernon Cameron, of my Cameron line.Family history has it that he was murdered in Boston, but no records are filed there on his death.
