Chase is from the Old French chacier (to hunt) — historically a surname now used as a modern unisex given name. Salmon P. Chase (1808-1873) — male; 6th Chief Justice of the United States; co-founder of the Republican Party; appears on the US $10,000 bill. Chase Utley (born 1978) — male; MLB All-Star.
Chase 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 Chase reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
