Yep, we're related.
My line is through her brother, John Robert Green.
So far I have been unable to acquire any more information on the location of the cemetery where graves were relocated from.
It is possible that the cemetery where some were buried and had to be relocated was not named Longstraw Cemetery, but could be an old cemetery of another name where graves had to be relocated to Longstraw cemetery due to becoming under water.
I'm just not sure at this point.
