Named after a house which existed at least as early as the 1811. Rosetta House and Farm are advertised for sale in The Belfast News-Letter in this year. Rosetta Lodge was described in 1825 as a ‘desirable country residence’, whilst Rosetta House was said to be 'about one mile from Belfast, the Newtownbreda Road’ in 1828 (Belfast Commercial Chronicle). The earliest occupier of the house known to us at present was Mrs Eliza Blacker, widow of Rev James Stewart Blacker, who had been rector of Keady. Eliza Blacker died at Rosetta in 1837.
The house was probably named after the Rosetta Stone discovered in 1799 and fully deciphered by Jean-François Champollion in 1822. The house, in turn, seems to have given name to Rosetta National School, now Rosetta Primary School. It is said that a plaster-cast replica of the Rosetta Stone was once displayed in the school, set into a wall, but that this disappeared in the 1920s.
"Resolved – That the name Rosetta Drive be approved for a new street on the property of Mr. H. Forbes, off Rosetta Parade". (22nd December 1931).
