Campion family.
Just found siblings of Jeremiah. Thomas, b. C.1808, JEREMIAH b. C.1809, Gifford died young, Henry, d. Australia, Rowland drowned 1861, William, Edward.
(No birth years after 1809 given)
Henry & Rowland came to Australia, arriving 1841 in Melbourne. I think Henry stayed in Victoria, where he died before 1860 . Rowland held land in South australia. Returned to Ireland and died shortly after in 1861, fell from horse & drowned near Fermoy, co. Cork.
Jeremiah,s son Charles was involved in Commonwealth Bank of Australia.
Believe this family were of Leinster inheritance line. Rowland resided Co. CORK.
