One of the things that kind of bothered me is having an apostrophe 'S' after the name John Williams. After researching it, I saw that it could be written and pronounced either way, but the majority showed that it should just be written as Williams' ...and pronounced just as his name sounds.
The plural of "Williams" should have an "apostrophe s" on the end. http://www.bartleby.com/141/strunk.html
