Could you be thinking of Aphra Morat who had two half sisters, Emma Muth, and Genevive Drake; a half brother, William VanDeWalker??? If she this the "Afra", she died May 15, 2005 in Rome, NY at 105 years old! She was born October 20, 1899 in West Branch, NY, daughter of Gorden A. and Bertha M. Windelspect Smith. She married Lewis S. Morat November 23,1918 in Lee Center, NY.
(My husband is related to the Drake line.)Hope this helps!
