My father, Ellis Masonhall, was born in the old post office building in the former town of Plymouth, Major County, Oklahoma in 1919. His sister, Edna, and his maternal grandparents, Benjamin Doan and Rebecca Sample, are buried in the nearby Plymouth Cemetery. I, at his request, am seeking historical information and any other data regarding the 'town' of Plymouth. Thank you in advance for any info you might be able to provide.
