Sterling is from the Old English steorling ("little star," referring to early Norman coins) — also referring to sterling silver (92.5% silver). Sterling K. O. J. Save Your Soul. (2022). Sterling Hayden (1916-1986) — male; American actor (Dr. Strangelove 1964, The Godfather 1972 as Captain McCluskey).
Sterling 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 Sterling reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
