Charles Oscar Mattson married Wendla Botmaster (Johnson) on February 13, 1904 in Berkeley, California. Wendla unofficially took the last name Johnson when she arrived in the United States from Finland. They had 5 children, 4 boys and 1 girl, during their short marriage. Unfortunately, Charles died only nine years after they married on May 13, 1913.
Charles and Wendla are John’s second great grandparents through his father’s maternal line (Shirley Gingg -> Agnes Mattson ->Charles Mattson.)
