I think the name George is fantastic, and many here in England&Wales seem to be on my wavelength, as he ranked at #12 in 2011.
So of course, it seems apt to put together a list of similar-ish names, should you not be enthralled by the idea of using a popular name. The majority of the names on the list fit into the old-timey-esque one syllable category.
Fitz
Once upon a time the nickname for names such as Fitzroy, this name has been used by itself since the 19th century. It derives from Old French, and means son.
Floyd
A relatively common surname, turned first name. The name itself derives from Lloyd: the slightly altered English version of Welsh name Llwyd which means grey.
Fred
Originally a short form of Frederick, but also of Alfred, Wilfred etc.
Fritz
A nickname for Friedrich, the German form of Frederick. During the First World War it came into use as slang for German soliders, just as the British soldiers came to be nicknamed Tommy.
Gage
More usually an English surname, it derives from Old French and means fixed measure. I remember being asked about gages in my driving test.
Gale
Another adoption of a surname as a first name, with Gale first being used as a first name circa the 18th century. The name derives form Old English and means light, pleasant, merry. It could also have links to Norman French word gaoile, which means gaol (or jail).
Gray/ Grey
Two spellings for the colour which is a mix of white and black.
Gregg
The name Gregg is usually taken as a short form of Gregory: the English form of the Latin name Gregorius, which means to watch.
Mal
Short form of Malcolm, and indeed the name of my very own Grandad.
Ray
Another name once simply a nickname, Ray has been used independently since around the 19th century. For me, this name is wonderful, not least because someone commented that I was a little ray of sunshine only the other day.
