Custom Sidebar On A Specific Pages

Hi guys,

Been working on a site for my local lodge ....

The existing site is below ...

http://kingsolomonlodge54.com

And I want to take the existing site and make it a wordpress site. I have setup a test blog below.

I want to be able to have a specific widget in a sidebar for say the history page show only links or content I decide are related to that page alone. I do not want a general sidebar widget displaying on certain pages.

Is there a plugin that can do this or is there a way to do this by adding a bit of code. Any info would be most appreciated.

I am using one of these themes ...
