Someone in my office recently asked me the derivation of my last name. I instinctively knew it was rooted in Great Britain and/or Ireland, but I had not looked it up in a while.
This is what I found HERE.
Recorded in the spellings of Green and Greene, this is one of the most widespread of English, and sometimes Irish, surnames. It is usually of pre 7th century origins, and derives from the word “grene” meaning green.
As such it may be topographical for a person resident by a village green or even a place called Green, or as a status name for a young man who played the part of the mystic and fertile “Green Man” sometimes known as “Jack in the Green”, in the May Day fertility celebrations. In this context “green” was symbolic of youthful ardour, spring, and the re-growth of nature.
Sometimes the surname can be of Irish origins, and a translation of the ancient Gaelic given name “Uaithne”. As this also means “green,” it probably has the same basic meaning and origin as the English form.
Green is the 37th most popular surname in the United States, I’ve read multiple places.
Truth is that I’m not certain of my English and/or Irish roots, though surely I have one or both, based on family lore. But on St. Patrick’s Day, I’m willing to yield to the wearing of the green, just in case.
