Maude (also Maud) is the medieval English form of Matilda — from the Old Germanic maht (might) + hild (battle). B. Yeats; his 1893 poem When You Are Old — "How many loved your moments of glad grace" — is among the most-quoted English love poems. Maude Adams (1872-1953) — American actress who created the role of Peter Pan on Broadway in 1905 and was the highest-paid American actress of her era. Maud Lewis (1903-1970) — Canadian folk painter.
Maude does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Maude reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
