Morag is a Scottish Gaelic name from mòr, meaning "great" — or possibly related to Mary. Morag is also the local name given to the legendary monster of Loch Morar (the lesser-known cousin of Nessie).
Morag is widely used in Scotland.
Morag 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 Morag reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
