Frederic Festus Kelly

Frederic Festus Kelly (died 3 June 1883) was a high official in the British Post Office. He was also the founder of Kelly & Co. (later Kelly's Directories Ltd.), which published the Kelly's Directory, a sort of Victorian-era "Yellow Pages" that listed all businesses, tradespeople, local gentry, landowners, charities, and other facilities located in a particular village, city or town.

In many sources, both contemporary and modern, his name is spelled Frederick. He should not be confused with his identically-named eldest son.
