My Grandmother was Loretta Elizabeth Tierney b.2-10-1906 in Charleston Mass.m.7-4-1926 to Edward Mervin Rich in Boston Mass.d.3-12-1988. Loretta's Mother was Margaret O'Brien, her Father was Patrick Joseph Tierney.In trying to research my ancestry for the past 20 years I've hit brick walls on these 2 lines. My Father never knew any relatives except his Father's sisters. He remembered meeting an older woman when he was young and he called her Grandma- name began with the sound "rock"? It was a big secret when he would ask anything about relatives. All that was said was that the name was changed but not why. The names Tierney and O'Brien entered the picture when my Grandmother died and I found her SS application. Sound like any relation?
