According to JRR Tolkien, the Mallorn tree is the home of the elves in Lothlorien.
This is the vision the Brothers Hildebrandt had of the Fellowship of the ring when they entered Lothlorien.
(the brothers also designed the famous Star Wars poster with Luke Skywalker holding his light sabre aloft)
Mallorn Trees had silver trunks and golden leaves.
The Lady Galadriel gave Sam Gamgee seeds to a Mallorn Tree and he planted them back in ‘The Shire’ where the Party Tree had previously stood.
When we first bought our home in Lorien Gardens, South Woodham Ferrers, our house overlooked a green, and I figured the name appropriate.
