Good Morning fellow keepers of the past. 
I am hoping that someone may be able to assist me in breaking down a brick wall.
I have my 5x Great Grandpa who was sent out to Australia as Convict in 1827 on board the ship Cambridge. He was said to be a labourer. Born in  Meath in 1801. His name is Denis Kilmurray.
He was tried at Trim on the 13th March 1827 for stealing a sheep (my very own Waltzing Matilda!) 
I have previously been advised that apparently there was a name change (the person telling me this did not elaborate on why, or whether it was to Kilmurray from something else or from Kilmurray  to whatever)  I have noticed the variant spelllings of the name.  I have also noticed a mass exodus of Kilmurray's to various parts of the world - Scotland, Argentina, the USA and a whole host to Australia. 
But back to Denis...
His death cert gives no extra clues as to his origins. I also have a number of other Kilmurray convicts I am sure are related given the rarity of the name, but have thus far not been able to "prove" . 
Hoping that someone can point me in the right direction.
