Stamatia is from the Greek Σταματία (Stamatía — to stop, to halt, that which stops the flow of misfortune) — from Greek stamatáō (to stop). Stamatia is one of the Greek feminine names — central to traditional Greek Orthodox heritage. Greek feminine name reflecting Greek Orthodox heritage.
Stamatia 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 Stamatia reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
