A cardboard box still stamped KEEP FROZEN, pulled from storage in Vancouver, held 114 letters Sam and Dora Diamondstein wrote each other between 1900 and 1926 — roughly half in Yiddish, the rest in English cursive. Their great-grandchildren had every letter transcribed and translated, then filled the gaps with family trees and living memory, turning a box of paper into a readable 26-year correspondence.
