Rhoda (Ῥόδη) is the Greek word for "rose." In Acts 12:13-16, Rhoda was the young servant at Mary's house in Jerusalem who, so overjoyed at recognizing Peter's voice when he escaped from prison, ran to tell the others without opening the gate — leaving Peter standing outside knocking.
Rhoda was the iconic CBS sitcom character (1974-1978).
Rhoda 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 Rhoda reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
