Apologies for resurrecting an old thread but this is definitely the gentleman I'm looking for! Thank you rusteze.
Joseph Gorry b.c. 1824. He married 1849 in Clogheen, Tipperary, Ireland to Mary Cavanagh. Moved to South Africa and served 1851, 1852, 1853, discharged 1857 from the 6th (Royal 1st Warwickshire) Regiment of Foot. Joseph's father was William Gorry, Farmer of Isle of Man and Mary's father was William Cavanagh of Fermoy, Tailor.
So far I have found two children of Joseph and Mary Gorry née Cavanagh:
1. Elizabeth Margaret Gorry ~20/03/1853 Holy Trinity, King William’s Town
2. Henry John Gorry ~05/03/1856 St George Cathedral, Grahamstown
I have found what may be a record of Joseph Gorry's death at the Itsayam Trading Station near Butterworth, Cape Colony. He is said to be crippled widower, living with the owner of the trading station, Charles Peter Wright, at the time of his death.
