//Micro-editing: American English has been moving for more than a century to reduce capitalization. Lowercase assisting bishop, priest in charge, rector, and diocesan, the last an adjective and not a noun, would be fine. You probably want to write his wife, Elizabeth, with the commas, to avoid suggesting that he goes in for plural marriage. He was surely on diocesan staff or a member of diocesan staff, not the diocesan staff itself (a large pole?). From 1986 to 1994 is preferable. From 1986-94 suggests that another period of paired years is to follow. They are the Harts; making nouns plural with an apostrophe is a mark of unskilled writing. They are within commuting distance, commuting already suggesting close, of, not to, their children and grandchildren.
