Easements- Surrounded by marshes also neighbors title messed up.

[Austin Bakich]

Hello, I am looking at a property right now that is on a county road. But the road frontage is all marshland or in a flood zone. The dry land sits in the back and the only way to get to the dry land is through a 250 foot stretch of a neighboring property. 

From what I can tell, the neighboring property has a very screwed up title. The original owner died 60 years ago and is still listed as the owner. 

I would need an easement for driveway and utilities. But my concern is, will I be out of luck if its hard to determine the owner of the neighboring property? Or will I be able to push through with it without direct consent from the neighboring property since I really don't have a way to the dry area?
