I may have some information that you are seeking. Approximately 20 years ago my Grandmother took me to the burial place of Fielding Allen, her great grandfather. I traced what I could from the tombstone, which spelled the given name, "Fielden."
Fielden and Mary are buried behind a church in a small settlement called Allen's Chapel. At that time, the minister's wife was unaware that the two graves were located on the property. I'll have to dig out more info from my very old hand written notes. I do not have very much information on the Allens prior to their arrival in Greenup Co., Ky. I have located a Fielding Allen in Faquier Co., Va., but do not have any proven connections. In many of the Greenup Co. Censuses, the name is often spelled Allin and/or Alin.
