Theophano (c. 955-991) was the Byzantine princess who married Holy Roman Emperor Otto II in 972 — bringing Eastern Roman court culture to the Ottonian dynasty.
Featured in the Lothar Cross iconography.
Theophano 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 Theophano reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
