Looking for a middle name.

For the boys name Theodore. Who will mostly be called Theo.

Since baby is due July 8th and I went a day early with my daughter I’m hoping to get to as close to the 4th as possible and we want a American baby name theme.

Theo is after Theodore Roosevelt, but I can’t figure out what goes with it that is also American history type.

Theodore Grant ( like U.s Grant) but I don’t like that just a example. Thanks for taking time to look!
