There is a wonderful website for the Adams County, Ohio, Genealogical Society.Adams County is right next-door to Brown County, Ohio, where Mt. Orab is located.If my memory serves me correctly, there was a Luther Purdin in Adams County, both Brown and Adams Counties are on the Ohio River in Southern Ohio.
The Society has in its collection:
James William PURDIN & Hulda MELVIN PURDIN Collection (Also BURTON)
information.I will get the Society's address and send it it another message.I have contended that the Purdum/Purdin/Purdon spellings in the above counties are the same family.The James William Purdin family may have come from New Jersey, however.I have just requested GenForum to add the surnames:Purdin, Purdon to the message boards.I was surprised when I checked that these surnames weren't already listed.
