Davenport was nephew of Arthur Thistlewood, the leader of the Cato Street conspiracy. He married Cecilia Hopgood, daughter of Thomas Burn Hopgood (1785–1860), the London silvermaker. His second wife was Eliza Clarendon Forbes, daughter of Captain John Forbes. Amongst his children were Horace Davenport the athlete and Cambridge University's one time representative in the 'mile dash' and Rev. John M. Davenport. Davenport's grandson was Hayward Davenport who later took over the business.
