When I was in Charleston, SC, I ran across a Huguenot (French Protestant) Church that had been on the same site since 1681. It's still a functioning Huguenot church. I had no idea Huguenots were still in existence. I was not there on a Sunday, so I could only peek in the window, but I wrote down their website address (see link above).
I also found when searching their website that they have a link to their prayer book, which can be found here. Its all online, and apparently was from the late 1700s. I took a gander at the Communion service, and it is similar but different in many respects to the Episcopal Prayerbook from about that same time. Take a gander at it, it's quite interesting.
