I am researching this regarding my ZAENGER line. Bessie May REIDLING married John George ZAENGER in Toledo on 8 Dec 1909. The marriage record says that her parents were named Henry L. REIDLING (born Pennsylvania) and Gertrude MUNCLAY (born Ohio). I can find JG and Bessie in the later census, but I can't find (yet) any trace of Henry L. or Gertrude in 1910 or earlier census. I certainly haven't searched all the options yet, but can anyone else give me any clues? Thanks.
ps - I can't find anything at all on the MUNCLAY surname, so I think this may be a misreading. Won't know until I find some other records.
