Hi ,   if you go to genuki/devon/hatherleigh you will find that there is an OPC for the parish , but also you will find various online resources like maps and directories which help pin point Upcott …….it seems to me that the Devon Heritage online transcription of the Trade Directory of 1791/8 is most useful ……..the Medlands were a family  and Joseph Oldham was lord of the manor , and so Medlands Upcott and Locks Upcott should be two farms in Upcott rather than two different places .  The Tuckers also get a mention …….
