I know you posted this note in 2003, but I'm just coming across it now.
NY State Senator Jeremiah Twomey (1874-1963) was my paternal grandmother's cousin. His father, Daniel Toomey (1855-1930) and my great-grandfather, Thomas Jeremiah Toomey (1859-1934) were brothers. The Senator appears to have changed the spelling of his name from "Toomey" to "Twomey" sometime in the 1920's.
Senator Twomey married Mary J. Monahan (1884-1963) in about 1900. They had one daughter, Palma J. Twomey (b. about 1907). Palma married Walter A. Sullivan (d. 1949).
I have more information if you're interested.
