My sister married Jimmy Eft in 1968, the same year his father, William Franklin Eft (23 Jan 1920-10 Aug. 1968 age 48) died from brain cancer which resulted from melanoma. Jim's only sister, Patricia Arlene Eft Moore (20 March 1943-6 June 1981) died of the same thing at age 38. James Franklin Eft born 23 March 1945 died July 23, 1988, also from melanoma/brain tumor. The family was from El Paso, Illinois and had moved to El Paso, Texas. Have any of the other limbs of the tree experienced this blight? Obiviously we do worry about my nephew and great-nephew and are taking all precautions, screenings, sunscreen--as you should as well.
