Maude (also Maud) is the medieval English form of Matilda — from the Old Germanic maht (might) + hild (battle). A top-20 US baby name in the 1880s and 1890s, peaking at #15 in 1881. Maud Gonne (1866-1953) — Irish revolutionary, suffragette, and the lifelong muse of W. 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.
Subject of Yeats's poetry and Aisling Walsh's Maudie (2016 film) on Maud Lewis.
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.
