Maija is the Latvian form of Mary — also linked to the Latin maia (May). One of the most common Latvian feminine names.
Maija Tabaka (born 1939) is the Latvian painter.
Maija 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 Maija reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
