Two photocopied scrapbooks (1866-1993) compiled by Evelyn Wendler Nelson documenting her family history. One scrapbook entitled "Our Olga," relates to the family of Nelson's mother, Olga Aberg Wendler; the other traces the family of her father, William F. Wendler. Both scrapbooks contain correspondence; birth, death, and baptismal certificates; genealogical charts; biographical narratives; photographs; and newspaper clippings.

The material related to Olga Aberg Wendler documents her birth and early life in G�tenberg, Sweden; her siblings and extended family in Sweden; her emigration to Red Wing, Minnesota (1905) where she worked as a baby sitter for the Aaron Bjork family; her work as a maid with the Gross family in Duluth (1907); her marriage to William Wendler (1909); the family's homes in Red Wing; and the lives and families of her children, Evelyn, Olive, and William.

The papers related to William Frederick Wendler document the lives of his father, Berthold A. Wendler, a Prussian emigrant and his mother, Katherine Lyon, the daughter of a French immigrant. The couple were married in St. Mary's, Pennsylvania (1866) and were early settlers of Red Wing, Minnesota. The bulk of the scrapbook material relates to Berthold and Katherine Wendler's seven children and their families.
