Arthur Gilligan [SEP] Early life
Gilligan was born in Denmark Hill, an area of Camberwell in London. He was the second of four children born to Willie Austin Gilligan and Alice Eliza Kimpton; his brothers Frank and Harold also played high-level cricket. The family had a strong connection with Sussex; Gilligan followed Sussex County Cricket Club as a child, and later played club cricket there. After attending Fairfield School, he was educated at Dulwich College from 1906 until 1914 where he established a sporting reputation in athletics and cricket. In the latter sport, he played in the school first eleven, as did his brothers; in 1913, all three boys played in the team.
