Maxine, I am sorry that I have not been able to identify the "Elizabeth Alderson" that you are looking for. I have looked through all my records on the Aldersons that originated from Rev. John Alderson, Sr. but I can find none that would match or come near to her birth date of 1797. I certainly suspect that she is of the lineage of Rev. John Alderson, Sr. but can not prove it.If I ever do find a connection I will let you know.Good luck!
