Armand was the name given to a vampire in Anne Rice's Vampire Chronicles. Before he came to Paris he was called Amadeo "he who loves God" but his name was changed due the nature of his new position, leader of a coven of vampires. Armand comes from the name Herman, which means "leader" or "military man."
Armand was the brother of Marguerite St. Just (the wife of Sir Percy Blakeney) in the classic novel, book, and movie "The Scarlet Pimpernel" by Baroness Orczy.
Armand Hammer (1898 – 1990) was an American industrialist and tycoon. It is a common urban legend that the brand name, Arm & Hammer, originated with or is related to him, as Hammer did own some stock in the company and served on its Board of Directors in the '80's. The truth is, Hammer only bought stock in the company as a joke!
I love, love, love, LOVE this name. It reminds me of the character of Armand from the Vampire Chronicles (mentioned above), whom I adore, and I also love it's pronunciation. And even the way it looks when written down! I may use it on a future son, and I'm surprised it's not more popular!
