Despite being the first settlers in the area, I don't think there's a single thing named after them.
Oaklawn Cemetery was Tampa's first cemetery, opening in the mid-1800s far away from the settlement around Fort Brooke, later the village of Tampa. Today, the cemetery sits in the middle of town, at the northern edge of Downtown Tampa. The oldest burials start around 1850, with regular burials declining by the 1940s, with the opening of newer cemeteries farther away from the city core. Still, I spotted at least two burials dating from 2007.
Oaklawn has a Catholic section, a Protestant section, and a slave section. I believe they recently discovered a bunch of unmarked slave graves. The first settlers of Hillsborough County are buried here, as well as a governor, a number of mayors, and lots of other important early Tampons (Tampanians); you can see the namesakes for a number of Tampa streets in Oaklawn.
The cemetery itself isn't creepy at all, but its location leaves a lot be desired. There are lots of seedy people lurking around the walls, and it is obvious that homeless live in the cemetery at night.
