From The Stone Cutters Journal, May 1933, p.16, Obituary
"GIBNEY - Thomas, a member of our San Francisco Local, died suddenly from a fall he received while working on the Post Office wall. He was taking down part of the granite when his crowbar slipped from under the anchor, causing him to lose his balance, and he fell to the ground some thirty-five feet below. The accident happened on March 17th, about two o'clock; Brother Gibney died the next morning at five. The late Brother was fifty-one years of age, and had been president of the San Francisco Local for a number of years. All members and friends extend sincerest sympathy and condolences to the bereaved family."
