Kerensa is the Cornish word for "love." Cornish is the Celtic language of Cornwall, revived in the 20th century after being dormant.

Kerensa 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 Kerensa reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
