Sonja's Henie’s mother was Selma Nielson. I thought she said her sister was Sonja’s mother or Sonja’s stand-in was her niece. (Ohhhh, I’m so confused!)

Was her name Edna G. Ellison? or Edna E. G. Ellison.
Her name is listed as Edna E. Ellison with no mother or father’s names associated in the California Death Records, online at RootsWeb. Verified against the SSDI records.

Her last Residence in the SSDI is listed as Newark, CA. That was the address of her daughter.

I’m not sure but this may be “Junior’s” family.
