Edna Barkow (?) to Ruth Sonnemann (age 7), 1 Aug 1925

Could be Edna Wilhelmina Barkow (1906-1987, married Frank Lipsky in 1933). She had an uncle and aunt living in Cambria or Lockport at the time, so she could have been visiting them as well as seeing Niagara Falls. This Edna was Ruth's second cousin.
