This is a name chain where you only change 1 letter from the previous poster's name. We'll see how much one name can morph before it becomes impossible to alter it anymore. If you come to a name that cannot be changed by just swapping out 1 letter, then you can swap out 2. If there's a double letter (like the "m" in Emma), then it counts as 1 whole letter (so you can change it to "Ella" and that counts as 1 letter change).
