I`m searching for ancestors and descendants of a Mrs. Frances Rideout from Los Angeles, because I found a letter from her, written to my great grandmother Luise Schmidt nee Kippenberg (she lived in Mecklenburg, Germany). The date of this letter was June 9, 1936 and the address of Frances Rideout was 627 So. Carondelet Street, Los Angeles, California, U.S.A. The letter ends with "your loving cousin Frances". Do you have any idea, how could I find out the descendants of her? Unfortunately, I don't know her maiden name.
