For the most part, I only change the names if I have multiple of the same name. For example, if I have a 58-year old Hula and I have a 15-year old Hula, I tend to change the 15-year old's name to Hula II. If it's a male, I change it to the name with Jr. after it or III if I have three of them. And then I just continue with that genre of naming, sometimes arriving at IV or V or futher if I remember to check for multiple names. Other than that, I don't change the name.
