I found the 1880 Federal Census and emailed it to you.
Apparently her father's initials were M. R. Do you have any idea who she might have married and where or when? You may be able to find out her birth date and place of birth on a marriage certificate.
As for Stella, the same applies. If you have any idea where and/or when they were married, you may be able to find the information there, or at least her maiden name. Then I'd go to Ancestry.com and look that up there. I'll keep looking.
