KEMPTON, Ind. (CNN/WISH) - An Indiana farmhouse that is rich in presidential history is attracting a lot of attention from Hollywood.

Shawn Clements bought this home in 2004 and started learning about its history. When he started to investigate its past owners, he got a big surprise.

The property was settled in the 1840s by Jacob Dunham, President Obama's great-great-great-great grandfather.

Since then, Clements has been working to preserve it as a tribute to the president's ancestors. He says, "We want to do something that we know that he's going to appreciate and he's going to be proud of. That's my number one goal."

When word got out about the house, Mister Obama attended a potluck dinner there just days before the 2008 primary election.

This week, a film crew came to document improvements and record the history of the home. Clements hopes a full-length film about the project will help to fund future renovations.

Plans call for the current project to be done before this year's election in November.
