Ole Rølvaag sent a postcard to his mother-in-law Karen Berdahl in Garretson, South Dakota shortly after the birth of their first child, Olaf Arnljot Rølvaag.
Caption on the back of the postcard reads: "Left to right: Rev. N.P. Xavier, Mrs. N.P. Xavier, Mrs. Christian M. Lunde, Mrs. Ole P. Homier, Ole P. Hoimyr." Mrs. Xavier and Mrs. Lunde were sisters; Rev. Xavier and Mrs. Hoimyr were siblings. Rev. Xavier was the first resident pastor of Ft. Ridgely and Dale Lutheran church, serving from 1876 to 1891. Nils Xavier was a Sami pastor.
