Hello,
My name is Simone and my great great Grandmother Margaret was a Pahl from Minnesota. She is the sister of Doctor Pahl of the Los Angeles Hospital mentioned in your post. My Grandmother (93 years old) was just telling me today about the time she spent there after a car accident on the 1940s. I decided to Google the hospital and saw your post. She knew your grandparents and has many stories about family life at that time. They are of German decent settling in Minnesota owning large sections of land. My great great grandmother (your great great aunt) married into the Saverien family who had two sons (your granfathers nephews) who became doctors. One Arnold Edgard Saverien was Chief for Staff at Citty of Angels and the other a surgeon in Sacramento. Both his nieces were nurses. Not sure what information you are looking for but write back a list of questions and I will ask Grandma Dorothy.
Sincerely,
Simone Anderson
