Manx Worthies
Arthur Caley 1829-1853
was born at Sulby (Lezayre). both his parents and grandparents were of ordinary stature and he had numerous bothers and sisters, none of whom were remarkable for their height. At the age of 22 he was 7'6" and weighed 21 stone and it is said that he grew slightly after that age. He was well built and so strong that he could lift a sack of flour with one hand and toss it into a cart. Early in 1852 he went to London where he was exhibited. Soon afterwards he was engaged for exhibition in Paris for 12 months. It is said that the sumptuous living he indulged in in that capital had such a bad effect upon him that he died of surfeit. The man who engaged him had insured his life for 2000 pounds.
