There are several counties named for Charles Carroll in parts of the country not known for friendly feelings towards the Catholic Church in the 19th century. (The one in Mississippi gets mentioned in the "Ode to Billy Joe"--"the Carroll County picture show"). His stature as the last of the Signers of the Declaration of Independence outweighed his religion (which many Americans may have been unaware of). Ironically he wasn't in Congress on July 4th, 1776, but arrived in time for the signing on August 2nd.
I believe that only in 1776, when Maryland broke away from Great Britain, did Catholics in Maryland get the right to vote and hold office. Despite that Charles Carroll had been prominently involved in the patriot cause well before 1776.
I do love history. I see counties named for people back then all over the country. When I can I try to track them down. It's so interesting. To bad they don't teach this in school anymore.
For instance there is a Henry County, Ohio. The high school is Patrick Henry.
