LOL!! According to Garand's descendants, and Julian Hatcher, the family name rhymed with "errand." (See wikipedia.)
Actually, it was Americanized when the family moved to the U.S. from Canada. (Garand was born in Canada.)
It is a very common name in France and Quebec, and is pronounced entirely different than any American pronunciation.
(More like "gair-aw" with no specific accent.)
Also, in the early 60s when I was in mandatory ROTC in college, it was called "M1 thumb," as if hours of marching with that 9 pound anchor in the nice hot, humid Florida sun wasn't punishment enough.
