I've found the follwing in the QUÉBEC DEATN INDEX (1926-1996): 1) NATHAN FELDMAN, b. 1904-07-20d. 1989-10-20 in Saint-Agathe-des-Monts, QC although he was a resident of Montréal, QC. He was a widower but wife's name not listed. His parents: Solomon FELDMAN+J. (no surname given). No further info. 2) NATHAN FELDMAN, b. 1910-09-09, d. 1966-07-29 while a resident of Saint-Léonard, a suburb of the city of Montréal, on the island of Montréal, QC. He was married but wife's name not listed. His parents: J. FELDMAN+ I. GREENSPANH. No further info. The other 2 NATHAN FELDMAN's are definitely not yours. There is no NATAN. Also, since listings for women are according to maiden names, I was unable to check for his wife, RUTH. As for Lilyan FELDMAN, there are none listed, nor under LILIANE. Only 2 LILI's & they're too old to be your couple's daughter. So, she may still be alive. Sorry I can't help you further.
