Ifrah is from the Somali / Arabic إِفْرَاح (Ifrāḥ — happiness, joy, celebration). Ifrah is one of the Somali feminine names — central to traditional Somali pastoral + Sunni Muslim heritage. Somali-Arabic feminine name reflecting Somali Muslim heritage.
Ifrah 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 Ifrah reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
