Ernest Hemingway has 12 grandchildren. 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 are members of this family.
Jack Hemingway had three children (Joan, Margaux, and Mariel), while Patrick Hemingway had one (Mina Hemingway), and Gregory Hemingway had eight (Lorian, John Patrick, Maria, Brendan, Patrick, Sean, Edward and Vanessa). Patrick is the sole surviving son of Ernest’s three, although at 85 years old, he is unlikely to have any more children. Margaux is the sole grandchild who has passed away at this time.
