Dr. Charles H. Yunker (Optometrist) wife Dr. Maud Yunker also Optometrist. Son Dr. Charles W. Yunker also(Optometrist) daughter Katherine Yunker Hattersheid m. Hugo Hattersheid 25 years her senior. Hugos' first wife Margaret. They had children Margaret and Hugo. Second wife Katherine lived in Sherman Oaks ca. 1920, in Glendale ca. 1930. I lost track of Katherine about 1952 where she was secretary-treasurer to a charity "Friends of San Fernando Mission del Rey". Katherine's descendents are the object of my search as there is a 1921 Van Nuys High School annual with her name in it that needs to ne reunited with her family.
