Lowell is from the Old French lou (wolf) + the diminutive -el — little wolf. Lowell, Massachusetts — historic American mill city (founded 1826); birthplace of Jack Kerouac and Bette Davis; the Lowell National Historical Park (1978) is one of the most-significant US heritage sites for industrial heritage. Lowell Mason (1792-1872) — American hymnwriter.
Lowell 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 Lowell reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
