Here are some possibilities:
* Misspelling: It could be a misspelling of a French name like "La Chloé," "La Chevelure," or "La Chapelle."
* Nickname: It could be a nickname derived from a longer name.
* Unique name: It's possible that "La Chélle" is a unique name, perhaps created by the individual or their family.
To understand the meaning, more context is needed. For example:
* Where did you encounter this name?
* What is the context surrounding the name?
If you can provide more information, I can try to help you determine the meaning of "La Chélle."
