Hi George, Sorry to jump in on this thread after so many years.
According to the Tunkhannock NewAge Examiner (24 Oct 2007) Astronaut Douglas Wheelock is son of Olin and Margaret Wheelock.His parents are natives of Factoryville, Pa which is where Elmer and Lottie lived.It seem likely you are on to something here.
BTW, Henry Wheelock (husband of Adelia Taylor) b Jul 1863 was the son of Augustus Wheelock and Lucinda (or Lucina) Conrad.Augustus was the son of Esek Wheelock and Sophia Steere. The lineage traces back to Rev. Ralph Wheelock (1600-1684) of Dedham and Medfield, MA This help at all?
