Hi Lorraine
My wife has Catherine Sharpe ch August 22 , 1824 Rushen in her line , she was the daughter of Robert Sharp and Margaret Crebbin , Robert son of John Sharp and Margaret Cowley.
My information has Robert Sharp dying in 1829 off the coast of Ireland after falling from a small boat , on the way to a fishing boat.
Not sure where I got the information from , but will search for it if you want the information.
Cheers
