Walter Knost married Ola Leola Nichols in 1920-1921? They are on the 1930 Census with her son Woodrow L. Davis. This is my husband's side of the family and would love to find out more info. I have a picture of Walter and Ola. I believe that Walter is the son of Christian Knost and Elizabeth Ackermann. I have a death certificate for her, Christian Henry Knost, Christ W. Knost, Henrietta D. (Knost) Hamm, and a Donald Rowles(son of Louisa Knost). Would love to discuss what I have wrong or right, and would fill in the blanks of what I know.
