Sometime during the late 19th century, William T. Orton and his wife Mary A. (nee Redford) Orton migrated from England. Their only child, Charlotte Ester Orton was born November 1873. Not much is known about the Ortons. They probably settled in the Germantown area. I don't know if Charlotte Orton was born in England or Germantown.
Charlotte E. Orton married Harry Greenwood. Harry Greenwood was the Treasurer of the Overland Motor Company and automobile distributor. I have no idea how or when they met.
