He was born at Giggleswick in North Yorkshire in England, one of five children of Marie Jane née Simon (1825–1908) and John Richard Blakiston (1829–1917), HM Chief Inspector of Schools and Headmaster of Giggleswick School (1858–1866). In 1880 aged 16 Clarence Blakiston joined the Merchant Navy as an apprentice at Cardiff[4] while in 1884 he was awarded a Certificate of Competency to serve as Second Mate.[5] In 1888 he married Glasgow-born Clementina Lindsay née Low (1864–1936)[6] and they had a daughter, Marie Blakiston (1889–1890).[7]
Stage career
After leaving the Merchant Navy Blakiston determined to try his hand at the theatre. His brief biography in The Play Pictorial review of The Blue Moon in 1905 recorded that:
Blakiston's first engagement was with a modern, but somewhat shady, repertoire Company whose manager cast him for juvenile lead, only because he possessed a presentable wardrobe. The thirsty members of the company were most eager to show him how his parts really should be played, but stipulated that the coaching was done in the nearest bar-parlour. Soon after joining, his manager called him aside and said, "My boy, you're too good for juveniles. When I see real talent I always help it on. I'll sacrifice myself by exchanging parts with you – I'll lend you my clothes (take care of them as it has taken me years to collect them), and you shall lend me yours." "Whereupon this gentleman" says Mr. Blakiston, "possessed himself of all my available suits and linen, and two weeks later gave me 12/- for two weeks' work, explaining with tears in his eyes that business was so bad owing to my inability to play such important parts. I never saw my clothes again. The manager's clothes (mostly rags) I sold for a few shillings, and got insulted over the transaction." After going through many vicissitudes Mr. Blakiston obtained an introduction to Mr. Edward Compton who engaged him as prompter, and thenceforth he worked his way up to the position of leading man, which position he retained for five years before trying his fate in town.[8]
By 1939 Clarence Blakiston was living in Ainsdale in Southport, Merseyside and here he died in 1943. In his will he left £221 3s 11d to Ellen Rosemary Blakiston.[24]
