I found Pliny Wood, married to Elizabeth Dove 17 Jun 1845. He entered the military (US Marine Corps Muster Rolls) on 20 Apr 1835 in Brooklyn, NY. The record is too hard to read to see what his position was. He re-enlisted on 19 Feb 1839 in "barracks near Boston". The record for 8 Mar 1843 shows him as assigned to the U.S. Frigate Macedonia. His Find-a-Grave record says that he died in Virginia and that he is buried in Massachusetts. Other than those bits of information, I can find no definitive records of the parents of Pliny Wood on Geneanet, FindMyPast, FamilySearch, My Heritage, or Ancestry.
