Berengaria of Navarre (c. 1165-1230) was the wife of King Richard the Lionheart of England — married him on Cyprus during the Third Crusade.
Distinct from Berenguela of Castile.
Berengaria 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 Berengaria reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
