Edwina is the feminine of Edwin — combining the Old English ead (rich, blessed) and wine (friend), meaning "rich friend" or "blessed friend."
Edwina Mountbatten (1901-1960) was the last Vicereine of India. Edwina Sharma is the heroine of Bridgerton's second season.
Edwina 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 Edwina reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
