Historical Context
This letter, most likely written by Beatrice "Evelyn" (Jones) Pedersen -- who was serving in the Eastern States Mission and released about the same time as Evan. Born in Henefer, Utah, she was apparently considering traveling home with the cohort in Evan's car.
Evelyn mentions needing a "clergy book." Historically, railroads offered discounted "clergy rates" for ministers and missionaries. These books contained coupons or permits that allowed for significantly cheaper travel, which was essential during the economic hardships of 1933.
The letter reflects a transition period. Evelyn is preparing to "break away" from her current situation to return home, moving from the active life of church service back to being "just folks living in a quiet way."
