* "Toe" as a synonym for "head": One theory suggests that "toe" in this context was actually a slang term for "head" in the 19th century. This would make "toeheaded" a literal description of someone with a "head" of light hair. However, this usage of "toe" is not widely documented.
* Association with "toew" (a type of bird): Some linguists believe that the term "toeheaded" might be connected to the now-archaic word "toew", a type of bird that was sometimes referred to as having "white" or "light" feathers. This connection could imply that the term "toeheaded" was originally used to describe someone with light-colored hair similar to a toew's feathers.
* Folklore and superstition: In some rural areas, blond hair was associated with luck, often with a "toe" of luck or a "toe" of good fortune. This association might have contributed to the development of the term "toeheaded".
Ultimately, the precise origin of "toeheaded" remains unclear. However, the likely explanation lies in a combination of historical slang, folk etymology, and the common association of blond hair with specific characteristics.
