So far three of the families with the D name are Jaguar, Monkey and Gol. They all have an animal name, Gol is close to Gull and the others are self explainable. Do you think this is a coincidence or do you think there's some connection that might get revealed later? They have some connection as Garp and Saul were both marines and Garp and Roger fought but I wonder if there's more to it than that.
