Ernest Hemingway had 12 grandchildren. They are Joan Hemingway, Margaux Hemingway, Mariel Hemingway, Lorian Hemingway, John Patrick Hemingway, Maria Hemingway, Brendan Hemingway, Patrick Hemingway, Sean Hemingway, Edward Hemingway, Mina Hemingway and Vanessa Hemingway.
Ernest Hemingway's oldest son Jack had three children (Joan, Margaux and Mariel), his middle son Patrick had one (Mina Hemingway) and his youngest son Gregory had eight (Lorian, John Patrick, Maria, Brendan, Patrick, Sean, Edward and Vanessa). Of Ernest's three sons, Patrick is the only one still living, but at the age of 85 is unlikely to father any more children. Margaux is the only one of the grandchildren who is presently deceased.
