Marjorie is the medieval Scottish-English form of Margery — from Margaret, Greek margarites (pearl). Stoneman Douglas High School in Parkland, Florida — site of the 2018 mass shooting — was named in her honor; the surviving students became the Never Again MSD gun-control movement. Marjorie Merriweather Post — heiress and Mar-a-Lago founder.

Marjorie 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 Marjorie reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
