On Wiki, we have the List of youngest grandmasters since 1950. What about WFMs (woman FIDE masters) instead of GMs?
Note 1: I really mean to ask about WFMs (females who obtain the female exclusive title WFM) and not female FMs (females who obtain the open title FM).
Note 2: WCM was answered here: List of records for youngest WCMs (woman candidate masters) since 1950?
