I have been able to find only two other geographic names which are taken from philosophers, Carla-Bayle in France, named after French philosopher Pierre Bayle, and Berkeley, California, named after Anglo-Irish philosopher George Berkeley. Unfortunately, though Locke did have an island named after him, none such exists today; the history of this makes an interesting story.
The Earl asked Locke to join his retinue, and in 1667, Locke moved to Exeter House in London, Lord Ashley’s home. Locke became an important part of the Earl’s household and he was appointed Secretary to two important bodies which Shaftesbury belonged to. One was the Lords of Trade and Plantation, which was a committee of the Royal Privy Council set up to advise on issues related to the newly established British colonies.
Locke was heavily involved in this new colony, drafting the Fundamental Constitutions of Carolina, as well writing various instruction to the colonists on how to make sure their actions in the new colony were consistent with the document. This was not Locke’s shining moment, for though he elsewhere wrote against aristocracy and slavery, the Constitutions, enshrined both of these in Carolina.
As Carolina was just in the process of being settled, and by some very influential figures, Ogilby was keen to include information and a map of the colony. Thus he approached Peter Colleton, the brother of one of the Proprietors, John Colleton, who wrote to John Locke, as secretary to Lord Ashley, requesting a map he could use in his book.
To my honoured frend Mr. John Lock
Mr. Ogilby who is printing a relation of the West Indies hath been often wth mee to gett a map of Carolina wherefore I humbly desire you to gett of my lord [Ashley] those mapps of Cape feare & Albermarlee that he hath & I will drawn them into one wth that of port Royal & waite upon my lord for the nominations of the rivers, &c.
