I have pretty "different" names chosen for future children. For example, I love the names Acacia (uh-kay-shuh) and Ryleah (Ry-lee-ah) for girls, and Beckett and Coen for a boy. The chances that a sibling or close friend would use those names is slim
That being said, we would likely be announcing chosen names early on to avoid this! Hoping that once people start thinking of *our* baby by Acacia or Beckett, maybe it would sway someone else to not pick the same name because the name is already associated with our baby.
However, its not the end of the world (IMHO) to have cousins with the same name. In my family, Hannah is the child(ren) of: (1) my stepsister, (2) cousin #3, (3) cousin #7, (4) my very close best friend, who came to family functions for years. They just get nicknames with it: Big Hannah (she's the oldest), Arizona Hannah (because of where she lives), Baby Hannah (the youngest so far), and Auntie Kat's Hannah.
