My greatgrandfather was Thomas Joseph Tierney he migrated in 1872 from England (he was born in Ireland abt 1850). His mothers name was Mary O'Brien daughter of James O'Brien and Katharine McInery. His fathers name was Michael Tierney. The 1880 census for Penacook NH shows: Tierney Thomas J. White Male Place of Birth Ireland Tierney Mary Mother White Female Place of Birth Ireland Tierney Bridget Sister White Female Place of Birth Ireland The 1900 census for Penacook NH shows this Thomas married with a family of 10 children. It also lists his mother Mary O'Brien Tierney as living with them. It states she is a widow and mother of 3. All 3 children were living in 1900 accroding to the census. I am trying to discover the name and what happen to this 3rd TIERNEY sibling. Any of this familar to anyone????
