To make it short, Murphy Sans is a libre take on the general feel of Gill Sans, based on the Open Source typeface Biryani.

Anyway, the author of this article
We needed a typeface for a website of a brand that made heavy use of Gill Sans. Our client didn’t have a license to use the font on the web, and also because of my general dislike for anything associated with Mr. Gill (look it up), we decided to create a new typeface based on the same ideas.
Instead of starting from scratch, we started with the libre font Biryani by Dan Reynolds & Mathieu Réguer.
We chose this font largely because the latin charset of this font ran in just about the correct width we needed, and it had a delightfully high x-height, which made it perfect for web use.

And most importantly for you, that means that the font remains licensed under the SIL Open Font License, and is therefore completely free!
