this is very interesting. Although apparently no relation to yours, I have Tierneys w/ Mass.(c.1835) and San Fran(1870) connections. David Tierney married Margaret (nee Ireland, but maiden name?). He was widowed by 1900. We believe that he died in Seattle, Washington of Brights disease on April 22, 1906. His sister Mary (Tierney) Burke, also widowed, may have perished in the San Francisco earthquake and fire of April 18-23, 1906. Of David's children, Daniel survived, but Mary is a ?? Daniel married Julia Buckley, and their only child, Margaret, married a man w/ McKenna surname.
