He was born in Peel, Isle of Man in 1879, one of four children of Hugo Flinn, wholesale fish merchant with wide interests in Ireland and Liverpool, and his wife (Mary) Kate (née Condren or Condran). The family's residence alternated on a six-month basis between Arklow, County Wicklow, and Kinsale, County Cork, according to the seasonal nature of the fish trade.
