Thomas ORR is believed to have been born somewhere within County Antrim, Ireland, around 1817. He was married in about 1843 or 1844 to Mary DUNLOP, and several children followed (and died) until her death in Belfast in 1868. Thomas found work in the late 1840s and early 1850s as a 'road master' or 'road overseer' in Malone, just south of Belfast, and during this period he and Mary were associated with the Balmoral Presbyterian Church in Malone. By at least 1858, and until he sold his business and retired in the late 1880s, Thomas ran a grocery and spirit dealer's enterprise on the Malone Road opposite the Botanic Gardens on Clink Hill.
Thomas ORR wrote his Last Will and Testament1 on the 7th of October 1897. At that time he was living within the household of his son-in-law and daughter, Hugh and Margaret LEDGERWOOD, at 239 Dalton Road, Barrow in Furness, Lancashire, England. Hugh Ledgerwood, himself also a grocer, was appointed as the sole Executor and Trustee of the Estate. Witnesses to Thomas's signature on the Will were Frank W Taylor and Arthur E Nicholson, both clerks to Frank Taylor, solicitor of Barrow in Furness.
