I purchased the subject RPPC (Real Photo Postcard) (not postally used) of a young girl, identified on the back:
"Margarete Luise Uerkwitz
Berlin born October 12, 1920
23 Months Sept. 1922."
This individual is listed in the 1930 Census data for Oakland (resided at 1490 34th Street), Alameda Co., CA. Born 12 Oct 1920 in Germany, she was the daughter of Herman H. Uerkwitz, born about 1887 in Germany, and Frieda M. (maiden name unknown), born about 1923 in Germany. The family immigrated to the U.S. in 1923.
