- Gaiwa-frey, "the peaceful country"
- Walah-frey, "the peaceful stranger"
- Gisil-frey, "the pledge of peace"
- God-frey, "the peace of God"
Any resemblance of these ancient names to "Gallifrey", the ancestral home of the Time Lords, is coincidental. Surely.
It may be that all these names existed independently, and were sort of merged together in people's minds. The only certain thing is the suffix -frey, which meant "peace," "joy," and "beloved," and is related to free, friend, and Frederick.
Spiritually, Jeffrey begins with an edge, a judgement, which gives rise to connection, relationship, and travel. This is then released into freedom, motion, and joy.
