Death of Michael Gavin

Hi

I am looking for the death of my great uncle Michael Gavin who was born in Derrycooraun in December 1885. He had a sister Bridget Gavin (My Granny) who initially emigrated to USA soon after 1911 census. Michael ran the family farm in Derrycooraun with his mum Catherine Gavin nee Neary. My mother told me that he drowned in a nearby body of water in his 20's and Bridget was summoned home to help Catherine run the farm. Bridget later married my grandad Patrick Quinn in 1917 in Islandeady.

I have been looking for Michael's death for a while without success. If anyone could help me I would be very grateful.

Thanks
