Take it to the location, include the county. Another option, is create and link a Free Space page to the location, if you have a lot of information... See the help page as well for creating Free Space pages, categories, or inserting images, among other things.
Sorry, I found the free space page: Gamble Mansion and Plantation
First: It's a state Park
Sub of first: It's a HISTORIC state park
It could also be linked to: Major Robert Gamble, President Jefferson Davis and Judah P Benjamin. (I'll put a comment out there for President Davis to see if someone can pick that up) Also, it could be linked to Florida Architecture 100 places. Some of these profiles or categories may not be created on WikiTree. Please feel free to do so.
