By the time of the 1851 Census of Ireland enumeration, they were living in south-west Belfast, County Antrim, in what is now Northern Ireland. Mary Orr died in Belfast in 1868. Thomas was a spirit dealer / grocer whose establishment was at Clink Hill in Malone, now a suburb of Belfast. Thomas Orr died in Belfast in 1901, having prior to his death for some time lived in Lancashire, England, with his daughter Margaret Ledgerwood.
