Eva was born Jan. 1904 and Rufus around the same period. It is my memory that Eva was the eldest. Information I have gotten from family sources is that Rufus was adopted by a family named Mantel or Mantal and his name was changed to Don. I cannot prove or disprove this information. Their parents are Theadore Heldt and Margaret/Maggie Gray. They had other siblings who lived with family members.
