(Dates on titles and offices are for the time period that the position was held.)
Note: There are probably date errors on these pages. Over time, I have discovered that some of the dates in the resources I used to compile this list are different from those in other resources. Sometimes they are off by a few days, sometimes a few years. I am gradually correcting the mistakes as I find them. In some cases though, we'll probably never know what the correct date is. Here's a list of the main sources I'm using to update and expand these pages.
