Anyone ever heard of the Gray Brothers?

Hello just curious if anyone has heard of the gray brothers I found a 78 of them on ebay? Because there are not as many well known fluters as fiddlers of the 78 era I thought they might be of interest to folks here. Seems to be tunes alright ? Anyone have a list of 78 era fluters? I used to seach for these in flea markets and antique shops never came across a flute but loads of fiddlers and ‘family bands’ CHeers, Patrick I’m not sure if this link works but

Never heard of 'em - but Hammy Hamilton’s book has a complete list of all recorded Irish flute music up until the date the book was published. The Gray Brothers, according to him, recorded this in 1928.
