It is possible that Clara Avenue was named after Clara Holland, daughter of Joseph Holland of Holland House. This certainly seems to be the case with Clara Park, Clara Road and the various streets named Clarawood which are located in Knock, close to the former site of Holland House. However, Clara Avenue is in Ballyhackamore, one mile to the west, so it is thoroughly possible it has a different origin. According to Ros Davies, Joseph Holland was a stonemason, artist, antique dealer, landlord and landowner of 800 acres of East Belfast. He died in 1900 in Cherryville Cottage, Sandown Rd. Clara died aged 18 in 1899 and is buried in Belfast City Cemetery.
