Hailing from a family of millers and general merchants since 1859, Eddie Kelliher was the only son of Maurice A. and Ellen Kelliher, who married in 1918. Kelliher had two sisters, Susan McKenna and Mary Walsh. Kelliher's father, Maurice A., the second son of Maurice J., was managing director of the family firm, M. Kelliher & Sons (1935) Ltd. until it was acquired by Edward, Maurice P. And John J. Kelliher in 1951. The family lived at “Park na Doon” house in Oakpark,
Tralee. The property, which was built by its previous owner, William H. McCowen in 1882, is a detached five-bay three-storey house featuring an on-site tennis court; an addition that was laid out by the Kelliher family. They resided there from the early 1920s until the 1950s when the family moved to
Listowel soon after Maurice stepped down from the family firm. Prior to the family moving to Listowel, Eddie met Doreen (née O’Sullivan), a
Valentia native, in 1940, whom he would eventually marry five years later on 16 August 1945. The couple had three sons, Desmond, Malcolm and St John; and six daughters; Christine, Laura, Brenda, Judith, Felicity and Genevieve. Two of Kelliher's daughters, Christine and Laura, have died. However, as of his memoriam, it is noted that he is survived by his twelve grandchildren and four great-grandchildren. One of his granddaughters, Daisy Kelliher, has been a cast member on the TV series
