Bakhita (بَخِيتَة) is the Arabic feminine of bakhīt — "fortunate, lucky, blessed" — bitterly ironic, since it was the name given by her kidnappers to the woman who would become Saint Josephine Bakhita (c. 1869-1947).
Bakhita 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 Bakhita reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
