Irish: anglicized form of Gaelic Ó Murchadha 'descendant of Murchadh' and Mac Murchadha 'son of Murchadh'. Murchadh combines muir 'sea' and cath 'battle'. Modern Irish forms are Ó Murchú / Mac Murchú. It is the most common surname in Ireland.
Spellings and related forms: Ó Murchadha, Mac Murchaidh, Ó Murchú, Mac Murchú, Murdock.
Murphy comes from Murchadh, "sea warrior", from muir (sea) and cath (battle).
Most surnames have no single "family crest". In heraldry, a coat of arms belonged to one person and passed down one line of descent. Sites that sell "the Murphy coat of arms" usually show the arms of one historic family that shared the name. Ours is different on purpose: an original design built from what the name means, which any Murphy can own honestly.
