Dafina is from the Albanian dafina (treasure, laurel) — possibly from the Greek daphnē (laurel). Dafina Sejdiu — modern Kosovo-Albanian figure. Dafina Kosumi — Kosovo-Albanian fashion designer. Princess Dafina — modern Albanian royal naming.
Dafina 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 Dafina reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
