ALEXANDRIA, Egypt, Mar. 19 (UP) —2/Lt. Ernest W. Spradley, of Rockwall, Tex., walked into a RAF party aboard a Nile houseboat recently and discovered one of the guests was 2/Lt. Josephine Martin, of Tilden, Tex., an Army nurse whom he used to date back home and with whom he corresponded after join ing the RCAF in 1940. — Today the couple are honeymooning in Alexandria, the first Americans in the services to be married in the Middle East. They were married Mar. 9 at Heliopolis by Chaplain Francis Early, of Phila delphia. Lt. Spradley was one of the first 50 Americans to join the RCAF. Trained in Canada and Engelard, he later was sent to Malta. While he was flying Spitfires there, Josephine’s letters stopped coming. Later he was transferred to the RAF air craft delivery unit ferrying planes across Africa, and it was on one of these trips that he went to the houseboat party. Spradley, who recently transferred to the USAAF, is ranked by his wife in seniority.
