Peter,
In response to this old post of yours...I am looking for links to my O'Leary roots. Mine are from Rhode Island.

I recall, my dad (Al Rondina) was close to one Tallman couple (Evelyn and ?) whom he referred to as his cousins. I'm not sure whether my Tallman's lived in RI or in a border town in MA.

My O'Leary connection is my grandmother, Anastasia O'Leary (Carpenter) who married to Frank Rondina in 1900.

Does any of this ring a bell for you? Many thanks.
