From the Belfast News-Letter – Monday 31 January 1853. Whiterock Road – OSNI (1846-1862) The second edition of the Ordinance Survey Map (1846-1862) indicates White Rock New Road. There was also White Rock Bleach Green. The Belfast And Province Of Ulster Directory 1877 lists several addresses for Whiterock Road. “William Sinclair was a local landowner who owned the Glenalina Bleaching greens in the 1860s.
