By searching for "Robert and Richard" in the Omaha World-Herald 1921-1930, I found this:
Omaha World-Herald, November 24, 1923, page 2
Fry Family Adopts Twin Alberts Boys
Mr. and Mrs. Albert J. Fry, 2605 Wirt street, today adopted twin boys, Robert and Richard Alberts, 2 1/2 years old. They were charges of the Child Saving Institute.
So now you have their original surname!
Child Saving Institute is still here: http://www.childsaving.org
If you provide your e-mail, I can send you a scan of the original article if you like.
