My mum always told me that she liked the first half of 'Gareth', but not the second, and the second half of 'Darren', but not the first, so she put the two together to come up with Garen (this was 1969). Very recently my aunt told me a different story, that my mum scrambled the letters of her own name (Margaret Anne) and picked out five, producing Garen. Whichever story is true (I think the first) - she made the name up.
I like my name. It's got five letters to match my surname and has a pleasing stamp. Up until I got on the Internet, I thought it was pretty much unique, though someone told me early on that Elvis Presley's twin brother was called Garen (actually his second name and not the same spelling, Jesse Garon Presely, he was sadly still-born).
When I did get on to the internet (in 1997) I found there were other Garens out there and I experienced something of the feeling that all Johns, Daves and Mikes must constantly have... that my name is shared. Most Garens the world over have an Armenian surname, and this does seem to be where its roots lie, although a number of more recent baby-name websites declare it as French, and that it comes from the word 'guard' (erm, which is garde). A friend of mine who recently had a baby, owned a mammoth book of 40,000 baby names, including Garen, of which it said it was English. I can't help but wonder if they got that from typing the name into Google and coming up with my website and looking at where I lived!
I do know of another Garen native to the British Isles. In the late 1990s I did some illustration work assisting comic artist Tony O'Donnell, and when he had a son around that time, he and his wife decided they liked the name Garen, so it became his too. He's not named "after me", as such (I've only actually met Tony once in person), but I feel honoured, all the same, that my name was the origin.
Update: I have since done a little research into the first name Garen, and here are some stats - from 1837-2005 there were 46 Garen births registered in England, Wales and Scotland; the first was in 1952; there were 4 in the 50s, 8 in the 60s (including me), 12 in the 70s, 7 in the 80s and 11 in the 90s. 33 were in England, 11 in Wales, and 2 in Scotland; 10 of those belonged to people with a non-UK heritage (going by surname), of which 5 were Armenian (the others Turkish, Arabian, Latin American, Punjabi and Hindu).
Garen is one of those names people never believe the first time they hear it, so I've always got the script ready to say "it's like Darren but with a G instead of a D", though sometimes I won't bother, and will endure being called Darren, Gary, Gareth or Geraint and on one amusing occasion, Garden. One chap I worked with for a few months even took to calling me Dave because my name just did not compute in his world. The most common mis-spelling is to give it two rs, and it is still sometimes mis-spelt by friends and even family. If I say my own name, Garen Ewing, too quickly, people tend to think my name is that of automobile-songster and pop-pilot, Gary Numan.
One popular use of the name Garen appears to be for fantasy characters in online fiction, as it lends itself to that random interlocking of syllable parts that I know so well from my role-playing game days when I did much the same thing (ah, Dorin Sharpesword, where are you now?) In fact, at the time of writing, the number one Google return is for Garen Muln, a human male Jedi master who "lived during the final decades of the Galactic Republic". Number two is for Garen Boyajian, a Canadian actor (with an Armenian surname) whose "dedication, drive and defiant pursuit of superstardom" I immediately support due to our invisible unusual-name bond (coincidentally, he also works to help raise awareness for Ewing's Sarcoma). As for me, I come in at number four, just after Tarot mistress, Nancy Garen (but I'm not counting the surname). I've seen one female Garen - Garen Thomas, an African-American children's editor and author.
Despite being one of those names you'll never find on a name-key-ring display in a tacky gift shop, there are a couple of places called Garen. It's the name of a ghost-town to be found on Highway 61 south of Forest Lake, Minnesota, founded in the 1890s. What I find intriguing about this place is that it was born of flame (a cattle-train stop built to placate the local farmers who were the victims of fires started by sparks from passing trains) and it pretty much died by flame (when the old school building burnt down in the 1930s, leaving only a roadside tavern into the 1940s). Garen is also a small town just outside Lindern, Germany ('garen' means 'cook' in German, apparently), and a village in Eidfjord, Norway.
So there you go... though the name has a Western Armenian heritage, in my case my mum just made it up in 1969. Well... you do keep asking!
