Captain John Moberly was born in St. Petersburg, Russia, of English parentage, in 1789. He entered the navy in 1801 when he was only 12 and by 1815 had become a post Captain, serving on a number of ships.
In 1834, Capt. John Moberly, was appointed to the rank of Admiral, in control of all operations appertaining to the navy, at the Penetanguishene Naval Yard on Georgian Bay. Although the naval section of the post was closed in that year, in 1835 Penetanguishene had 40 naval personnel known as a batteaux establishment for the conveyance of provisions, military stores, etc. and a general sale of craft and naval and marine appliances was ordered in 1832 and continued for some time.
While stationed in Penetanguishene, Captain Moberley was a major fundraiser for the building of an Anglican church of St. James on-the-Lines in 1837. He was later buried in the graveyard of the church.
In 1825 Captain Moberly married Miss Mary Fock, daughter of General Fock of the Russian Imperial Service. She was born in Sebastopol, Crimea, where her father was then stationed. General Fock, who was a member of a Polish family of distinction, had command of the Russian Imperial Artillery at the famous Battle of Borodino in Russia which preceded Napoleon's entrance to Moscow in 1812. Of this union were born nine children, six sons and three daughters.
Mary born at Sowerby, Yorkshire, 1829; married in 1850 Sir Harford Jones-Brydges, Radnorshire, Wales.
George Moberly, who was also born at Sowerby, Yorkshire in 1830, later became a barrister in Collingwood, Ontario and married Fanny Maria, third daughter of the late Col. E. G. O'Brien, Shanty Bay, Ontario.
