I am currently recording the graves at Dreamland Cemetery. I am curious to know how your search is going regarding this family. I do have a side note on Jennie Vester. She is buried next to Joseph Hastings and his wife. Possible that these are her parents? And there are Swaringens buried out here. The name is close to the spelling that you have; however, there may be Swearingens out here, I just have either not come across them or they are in my notes and I have not entered them in the database.
As regards to the other surnames that you listed, do you have any first names to go with those? I will be happy to look for them in the cemetery records for you.
