I don't know if this connects, but here is what I have on my wife's DAHILL family from Arlington (Boston) MA.It looks like this Thomas DAHILL was probably born before 1850, and probably from Co. Cork:

Cork, Ireland +Katherine Anne O'NEIL b: 14 Sep 1870 Arlington, MA m: 21 Jun 1893 Arlington, MA (also registered in Somerville, MA) 3 Thomas DAHILL d: Nov 1977 +Helen m: Somerville, MA 3 Katherine DAHILL +William WHITTIER 3 Margaret DAHILL +W.

Jeremiah Dahill was a bulding contractor.He was married at St. Agnes Church (formerly St. Malarchy) by Rev. J. H. Mulcahy.
Jeremiah Dahill's wife, Catherine O'Neil, was baptized 18 Sept 1870 at St. Peter's Church in Cambridge, MA.Her middle name was Anne.She was born 14 Sep 1870.The Godparents were Nathanial BULLOCK and Julia O'NEIL.Her parents were Patrick O'NEIL from Co. Cork, and Kate FOGERTY.
I don't have any more info on them.Does this look familiar to anyone?
