Gardner is a surname of English, Scottish and Irish origin.
[2] Other sources claim that it is derived from the old English words gar-dyn meaning "warrior", "one who bears arms".
[3] In Ireland, the surname is an anglicized form of the Gaelic Mac Gairnéir.
[4] Variants include Gardyner, Gardener, Gardenar, Gardinier, Gardiner, and Gardner; the last two are the most common today.
[5] There is a tradition[6] held by some of the descendants of William Gardiner (son of Benoni), son of George of Newport, that William won his crest at Acre in 1191, by chopping through the shoulder of a Saracen who was about to kill Richard Coeur de Lion or Richard the Lionheart, hence the Saracen's head on the coat of arms.
