I believe you are referring to my grandfather. He was married to Anna Mullar nee Poch. Her first husband was killed in a mine accident.
Frank & Anna Roboch had the following children, which are in order of birth: Frank, Annie, Josephine, Mary (my mom now deceased), Edward and Victoria, who died when she was very young.
Anna had two children from her first marriage to a gent with the last name of Poch. The eldest was Louis, who was killed overseas in WW2, and Tony who passed away in Nelson, British Columbia, Canada.
