The son of John Hearn (1866–1920),[1][2] and Joan Hearn (1866—), née Brown, Clarence Hugh Hearn was born at Tocumwal, New South Wales, on 13 November 1905.
He married Moira Lillian Morrison (1912–1991) in 1936.[3]
"The [Essendon] committee were very pleased to receive the permit of Hearn from Rutherglen. Hearn, who won this year's Stawell Gift, comes to Essendon with a fine reputation. His form on the track confirms all the glowing tributes that have been paid to his ability, and his marking against some of the aerialists of the side has left nothing to be desired. Hearn is equally at home at half-back, centre or half-forward, and has been included in to-morrow's side on the half-forward wing." — The Age, 10 May 1929.[5]
Hearn spent his early career at Essendon as a defender, mostly at half-back. Despite having managed just two goals from his 31 appearances coming into the 1931 VFL season, Hearn was given a role up forward and kicked 31 goals for the year, 24 of them over five consecutive games.[6] He was used both as a forward and a back for the rest of his time at the club. He kicked seven goals as a full-forward twice: against Fitzroy in 1932 and Hawthorn in 1935.
At its hearing on 10 May 1934, with Hearn having pleaded guilty to striking in retaliation, the Tribunal declared both players guilty: and having determined that Morrison was "the aggressor", disqualified Morrison for six weeks, and Hearn for four.[8]
