Some nicknames are generic nicknames and not really related to any full name. These two are just a few examples.
Birdie comes from bird, lady bird or baby bird. Most famously, was used for Claudia "Lady Bird" Johnson, the former first lady. Sometimes it is related, like a woman I knew whose full name was Robin. But it has been a nickname for several dozen unrelated names.
Chip often comes from "Chip off the old block" referencing a son who is similar to his father. It can be related to the full name, but usually isn't.
Other similar type nicknames, Junior, Trey (for any third son/child), Quint (for a fifth son/child), Buddy, Sweet pea, Belle (often associated with annabelle or clarabelle, but sometimes unrelated to the full name) and many more.
