Archdeacon John Caley a Cms Missionary Who Basically Belonged to England

Sir,
I'm Vinil Paul from India (Kerala state). I'm looking for the family history of Archdeacon John Caley, a CMS missionary who basically belonged to England. He established a number of churches in our locality (1871-1905). He was a great missionary in that period. His writings were available in CMS Missionary periodicals. He established lot of churches for former slave caste peoples. In 1905, he return to England and he had no Children. Really I wish to know about more details, If anyone could help me to get more details about the great missionary I would be greatly obliged.
