I've included two ancestor charts. The first includes all Jack's ancestor's on one page. Even though it is compressed it may be hard to follow.
The second chart is a paged version showing 4 generations on a page. Click on the end of the line arrow to go to the next page.

If you are a descendant in a descandant chart you can use Control-F to find yourself on the chart. The names are first name, middle initial (followed by a period), last name.
 
There is a legend defining the meaning of the various colors on the charts on the top and bottom right of most charts
