According to Dean in his book on gate lodges there was a house and lodge called Brookvale pre 1832 which had been built for William Sinclair. The Ordnance Survey map 1832-1846 shows a large building and also a gate lodge to the Brookvale estate. Both house and lodge were demolished by 1878 to make way for Belfast Royal Academy. (Dean) The surmise is that the Brookvale streets take their names from the Brookvale estate.
"On the application of Mr. William Bennett it was Resolved – That a new street on his property situated off Brookvale Street be named Brookvale Parade". (12th June 1928)
