Can you help identify the people in these Cone family photographs?

Recently, Flora Cone Brim's granddaughter Flora, sent me a couple of old family photographs asking for help in identifying people. Both cousin Stephen Zerwas, William Laurence Cone's grandson and I have had some luck but we still need help. Please take a look at the pictures below and see if you can help.

Identified so far... from left Frederick Naaman Cone, Helen Brown Newton Cone,
Row behind second from left, Charles Newton Cone. Date and location is unknown.
Photograph from the personal collection of Flora Long.

My grandfather, Charles Newton Cone, wore his hair in this style while he was in college. He graduated from Fairmont College, now Wichita State University, in 1920. The fir tree in the right background may indicate that it was taken after the family moved to Oregon. They are still in Mapleton, Utah in the 1920 census.

Frederick Cone with wife Helen and daughter Mary E are listed on line 39-41.

In January 1921, Fred has registered his Ford truck at R 3, Salem, Marion County, Oregon.

The next photograph is taken quite a bit later.

So far identified... from left standing: Bob Brim (?); Tommy and Molly Cone Acheson; Flora Cone Brim;
three unidentified women; Helen Newton Cone; (standing behind) William Laurence Cone holding
daughter Catherine; Helen's husband, Frederick Namen Cone; William's wife, Wauneta Watts Cone; Charles Newton Cone holding son Frederick Allen Cone; and wife Hazel Allen Cone. Seated third from left, Charles Newton Cone, Jr. Photograph from the personal collection of Flora Long.

William Cone's daughter Catherine was born in 1934. My Dad, who is seated, was born in 1927, his brother Fred was born in 1933. Fred appears to be no more than 3 years old in this photograph so perhaps the photograph was taken in 1935-36. It is most probably taken in Oregon.

If you can help, please comment on this post. Thank you for all your help.
