Viorica is from the Romanian Viorica — bluebell, harebell from Slavic viola (violet/blue flower). Viorica is one of the Romanian feminine names — central to traditional Romanian Orthodox heritage. Romanian feminine name reflecting Eastern European heritage.
Viorica 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 Viorica reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
