The Sequoia or Giant Redwood would have been planted as one of the specimen trees of the Brandon Hall estate. Edward Bliss made his money selling gun flints during the Napoleonic wars and used it to buy and create Brandon Hall and the surrounding land. Many of the unusual trees planted in what is now Brandon Country Park and the wider Thetford Forest are a legacy of this.
