Yes we have a Miller that married into the family. Virginia Diehl, married a Miller from Bellaire, Shadyside or Martins Ferry, Ohio. I have no information on her husband.
Because she married sometime after the 1930 census (most likely in the 1940's) I cannot find any records for her or husband. If I remember correctly they lived in Shadyside in the mid 1950's.
