Yarmouth has been a settlement for over a thousand years, and is one of the earliest on the island. The first account of the settlement is in Ethelred the Unready's record of the Danegeld tax of 991, when it was called Eremue (as on the sign), meaning "muddy estuary". The Normans laid out the streets on a grid system, a plan which can still be seen today. It grew rapidly, being given its first charter as a town in 1135 (as on the sign. The town became a parliamentary borough in the Middle Ages, and the Yarmouth constituency was represented by two members of Parliament until 1832.
In St James' Church there is a monument to Sir Robert Holmes, aventurer and governor of the Island. The statue, headless, was captured from a French ship, and was thought to be intended a memorial to Louis XIV. Sir Robert's head completed the statue, but is of somewhat inferior quality.
The Yarmouth were lost, thrown overboard by a drunken sea captain, who thought he'd stolen a case of wine. When he found that it only contained books, he threw it overoard.

If anybody would like to expand this series please do. I would just ask that you let Smokeypugs know first so they can keep track of the Village Sign numbers and names to avoid duplication.
