Where in Missouri are you looking? I have Munger's in KAnsas City, Jackson, Missouri during that time period. Charles R. and Marion Shepard Munger came from Syracruse, New York in the 1880s they had three daughters, Grace, Edna, and Bertha. Marion died and Charles married an Elizabeth Eberhardt (b: MO ) They had three children Ruth, Florence and Charles Truman Munger. Since 4 of the daughters were married by 1920, possibly these could be one of thier children or even cousins.
