Thanks for all the input. I actually decided to spend some money with an experienced real estate lawyer, and here's the legal opinion in Georgia:
Easements granted survive any change of ownership of the property, unless extinguished. So, in my case, the original owner still has the easement, along with the second owner, along with any subsequent owners if the language remains in the legal description of the property and is not extinguished by a quit claim deed from each (or is abandoned [not used] for some undefined significant amount of time, like 20 yrs).
It just doesn't seem right that people who were not a party to my transaction have rights to my land that I did not explicitly grant, but that's the way it is.
Thanks for all of your help.
