It is not a place name, but is the Irish language name of the street in Cahersiveen (the more common spelling, and certainly the form used locally), meaning "top, or, high street", where Sigerson Clifford (1913-85) was brought up. He was actually born in Cork but his family moved to Kerry when he was but a nipper. I posted quite a lot about him on one of the other Threads a while back.
