Coincidentally, I looked into the Prior family some months back, so for anyone interested:
Charles Bolingbroke Leathes Prior was a solicitor, J.P. and Official Receiver for Norwich and Great Yarmouth. His elder son (there were also two daughters), John Gilman Leathes Prior (1915-2009), was vicar of Holy Trinity, Springfield and of Christ Church, Guildford, int. al., also serving as a Chaplain to the Forces 1941-6. He had four sons and a daughter.
C. B. L. Prior's father was Leathes Prior (b. 1854), also a solicitor; he married Fanny Ellen, dau. of Charles Nathaniel Bolingbroke.
Leathes Prior was the son of Henry Prior, a Major (perhaps later attained higher rank) in the Madras Army. Henry Prior married five times, with issue from all of these marriages except the second. Leathes Prior was the eldest of three sons from his fourth marriage (in 1852), to Amelia Mary, dau. of James Browne Tompson (seemingly the individual of that name that was a Norfolk curate). The name 'Leathes' comes from Henry Prior's second wife, who bore him no issue and presumably died after only a few years (given they married in 1836, and he married his third wife in 1841); this second wife was Elizabeth Leathes Mortlock, dau. of Sir John Cheetham Mortlock, a commissioner of excise, of a family of bankers.
The record of Henry Prior's fourth marriage gives his father's name as George Prior.
