Ermentrude

Ermentrude was the name of two medieval queens of France. Despite these distinguished beginnings, this antique name is unlikely to catch on with contemporary parents, perhaps because the first syllable may sound unattractive to the modern ear and the last two syllables are the equivalent of intrude. Then there's that rude final syllable. English variant Ermintrude is equally unlikely to find favor.

The numbers bear this out: Zero baby girls were named Ermentrude by any spelling last year....or in 1880, 1920, 1950, or 1990.

Pronounced ER-men-trood.
