Minnie Allen Muckler (Richmond), my great-grandmother, lived from 1868-1958. At one point, she was in Tacoma, WA with her husband Clarence Muckler and daughter, Charlotte "Bernice" Muckler. Charlotte graduated Lincoln High School in Tacoma in 1921.
I would like confirmation that her mother is Amelia Mary (or Mary Amelia) Cobb - or another Cobb, entirely. I cannot confirm Minnie's father - even though her death certificate confirms that Minnie's mother's last name was Cobb.
If I can confirm Minnie's mother or father, I'd stop being so stumped.
