"What's in your name?" Consonants and vowels .. ??

I have French Hugenot ancestors too ..and surname was my Great Grandmother's maiden name (changed by German grandfather from Hahn = "hen" in German).

Challis apparently from L'Escalier range of mountains (shaped like a staircase) in Pas de Calais in northern France. First noted in London/ Essex in 16th century apparently.

Then married a Cook - pronounced "Nkhuku" when I lived in Africa as a pun on the local African language word for chicken.
Cluck!
'Scuse me while I go lay an egg or something :)
