There are baby announcements, photos, and a number of letters sent from Honolulu and California military bases during World War II.
Frequent names in the letters include Dr. Alstrup Nordahl, James Baldwin Johnson and Hilda Johnson, a nurse.
The city of Roseville posted a photo and message on its Facebook page hoping to spread the word.
The message reads.. "The family had roots in Yreka, California; Roseburg, Oregon; Kelso, Washington; and Longview, Washington. If you're from the Nordahl/Johnson family, please email our Social Services Unit at PoliceSocialServices@roseville.ca.us."
