This is supposedly the Carney family crest. This scan comes from one of those wall-hangings you can buy at various ethnic stores; this particular one I purchased at The Leprechaun Shop in Clare, Michigan, USA. The basic crest itself is also pictured, in black and white, in “The Book of Irish Families Great and Small”.
Items with the crest, and other variants of it, can be purchased at http://coadb.com/index.php?search=carney.
