Daughters of the American Revolution

I've known for sometime that I am descended from a Revolutionary War Patriot, but just now looking into applying for membership to the DAR.  Yesterday I was proposed for membership and approved.  Now I need to complete my PplicTion and gather my supporting documentation.  Oh my!

I've spent my free time searching for my documentation.  Couldn't find it online so am going to have to visit the Iowa Historical Library.
