My mother, Mary Frances Davis, was born in Topeka 12/05/1913 to my grandparents, Charles Henry Davis and Katherine (or Catherine) Malone, who moved to Britton, OK about 1919. The Davis' operated a bakery in Des Moines, Iowa and in Britton, so may have operated a bakery in Topeka. I do not know the names of my ggrandparents or of my grandfather's siblings and am new to genealogy. Any suggestions of sources I could explore? Thanks.
