Errol Flynn’s Relatives in Sligo, Ireland?

The Mail bag brings a request by Errol’s daughter Rory Flynn:

She writes –

“My grandfather‘s brother lives in Ireland (one of them) the other lives in Sydney that I know (if they’re still alive), and I know they have children but I’m just wondering if anybody has any connections to Sligo, Ireland … and knows of any of the relatives of Errol that still live in there?”
