I'm trying to help my cousin find her half sisters. She's Roberta "Bobbie" [ELY], only child of Ethel [NESS] & Ralph Byron ELY (Sept. 1913, near Peoria, Peoria Co., IL - July 1964, San Francisco, CA; div. Chico, Butte Co., CA). Ralph was son of Philip ELY & Pearl PHILIPS. He was serving in the USAF in Germany, 1944+, and married Merceds / Mercedes WETZ, of Wiesbaden, Germany. They had Jean, b. Apr. 1946; Pearl, b. Mar. 1947; Edith, b. Apr. 1948; & Joan, b. 11 Dec. 1950. Ralph's sister recently gave "Bobbie" a photo of the girls taken in 1952. Do you have any clues?
