Why is it inaccurate to say that momma was Mrs.Henderson's pseudonym?

It's inaccurate to say that momma was Mrs. Henderson's pseudonym because "momma" refers to a familial role or term of endearment, while Mrs. Henderson is a formal title associated with a person's legal name. Pseudonyms are typically used for artistic or public personas, whereas "momma" conveys a personal and intimate relationship. Thus, the two terms serve different purposes and contexts, making the comparison misleading.
