Marja is from the Finnish Marja — berry + Finnish rendition of Maria (Hebrew Mary). Marja is one of the Finnish feminine names — central to traditional Finnish Lutheran + Finno-Ugric nature-naming heritage. The Finnish marja refers to Nordic berries (mansikka strawberry, mustikka blueberry, puolukka lingonberry, lakka cloudberry, vadelma raspberry) — central to Finnish jokamiehenoikeus (Every-person's-right foraging tradition).
Marja 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 Marja reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
