Diane Kelly's information is intriguing. She mentions that her gr-gr-grandmother's sister, Jane Eliza Moore, married William Jory.
My gr-grandfather was Edward Jory, born on Bodmin Moor, in the parish of St Cleer, near the village of St Ive, Cornwall -- apparently on 15/11/1839. He had a brother William; and his sister Martha married a Caleb Moore.
Here are some more particulars.
Edward's parents were William Jory (died 1869) and Martha Allen. They were Methodists.
Edward's siblings were William, Jane, Sophia, Martha (married Caleb Moore), and Thomas. They are all mentioned in the 1864 Cornwall census.
Edward came to Victoria, Australia in 1863. He was a miner, and died in 1892 of miner's disease In 1870 he married Rosina Heal, who came from Taunton in Somerset. His children were Alice, William, Edward, Rosina, Mabel, Holford (my grandfather), Harold and Frank.
At least two unrelated Jory branches came to Australia from Cornwall, at least one to South Australia and at least one to New South Wales. All were apparently miners, and I'd guess that they were "assisted migrants" who were bonded to work in the mines.
The name "Jory" is evidently French. It just means "George", and comes from the base-Latin "georius", for farmer. There is a French Jory coat of arms of three red chevrons on a gold field; and its simplicity indicates that it is very old. There are three villages named St. Jory in France. Possibly the name originated at the time of the Crusades. According to Butler's Lives of the Saints, St George was a soldier who was martyred in Asia Minor in the fourth century, and thereafter became much revered in the Byzantine world. During the First Crusade the crusaders (mostly French) picked up devotion to St George on their way through to the Holy Land; and the saint allegedly appeared to one of the leaders, Geoffrey of Bouillon, before the crusader attack on Antioch, in which they were successful. Thereafter the cult of St George took on in a big way in France. St George was certainly known in Western Europe before then -- centuries of pilgramages to the Holy Land ensured that -- but it's my (romantic) guess that the French name Jory took root soon after the First Crusade.
