John Logan "Jack" Brown was born on 15 October 1913 at 27 Rochester Street, Belfast, to William Blair Brown and Margaret, née Logan. The family later moved to 45 Haddington Gardens.
He married Annie Mills at Ravenhill Presbyterian Church on 20 March 1940. Their first son, John Logan "Ian" Brown, was born on 27 January 1941. Their second, Stephen Brown, was born on 13 September 1942. A third, Michael Brown, was born in 1944, and a daughter, Elizabeth Jill Brown, followed on 5 September 1955. By 1944 the family was living at 108 Ardenlee Avenue, Belfast. By 1958 they were living at 442 Ravenhill Road, Belfast.
After qualifying with a Belfast firm of Chartered Accountants, he joined the Northern Ireland Housing Trust as Finance Officer in 1948. The Housing Trust had been set up in 1947 to provide and allocate public housing alongside local councils. For its last year, 1971, he was acting General Manager, and in January 1972 he joined its successor body, the Northern Ireland Housing Executive, as Director of Finance. The Housing Executive took overall public housing in Northern Ireland from the Trust and the councils. He was awarded the OBE in 1976.
Ian married Vivien Derbyshire. Stephen married Paddie Magill in 1967. Michael married Margaret Easton. Jill married Gordon Howell, but died of breast cancer in 1998.
After Annie died in 2004, Jack left 442 Ravenhill Road and moved in with his son Ian and his family at 2A Mayfair Avenue. He died in the Ulster Hospital in Dundonald on 9 January 2009, having spent his last few weeks at Towell House nursing home on the Kings Road. His funeral was at Mountpottinger Methodist Church, and he was buried at Dundonald Cemetery.
