Glikl is from the Yiddish-Germanic glik (luck, happiness). Glikl of Hameln (1646-1724) was the German-Jewish businesswoman and author of one of the first known autobiographies by a Jewish woman — written in Yiddish for her children after her first husband's death. A vivid account of 17th-century Jewish life, business, and motherhood.
Translated into many languages; Yiddish literary milestone.
Glikl 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 Glikl reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
