The Clowry surname is and anglicised rendering of the Gaelic surname Mac Labhradha which is possible derived from the Gaelic term “labhraidh” which means literally, “spokesman”.

Gary Clowry suggests..
Clowry… in Irish it is MacLabhraidh and it means speaker, spokesman or advocate. Decending from Eochaidh Labhraidh MacFhogartaigh, Lord of Fermanagh. I think is was Cromwell that asked us to leave, in a friendly sort of way… as you can imagine.
