I am doing a family tree and have come up with some interesting info.
I have traced my great-great grandfather to Carroll Co. Maryland, born in 1818. His father was born in Ireland. He was the town's shoemaker. I find it fastinating to know that my family was here during the War of 1812. Maryland has lots of history with the Star Bangle Banner being written by Frances Scott Kay of Carroll/Frederick counties.
You are talking about my neck of the woods now! Actually, I was born in DC, but now live in the county south and east of Carroll.

We've been to the Carroll County Farm Museum which I'm sure you'd enjoy. The Carroll family was quite important to our state.
On my hubby's side, his mom did all the research - tons and tons - even going to remote, small graveyards in the south - his mom can trace her family back to Daniel Boone. Thus, our girls are eligible to become Daughters of the American Revolution. However, we've never participated with that.
My mom is adopted and has a mix of German, French, Scottish and Irish depending on which day you ask her. Hope she never drops the Irish part.

My dad is German and French, but no one has traced his side of the family back as far as my mother in law did for hers.
