Hengest and Hors (*Hench and Horse)

Old English Modern English
Name Hengest, Hengst *Hench (see the note below)
Pronunciation /ˈheŋɡest/, /ˈheŋɡst/ /hɛntʃ/
Etymology From Proto-Germanic *hangistaz “horse, stallion”. Cognate with Old Frisian hengst, Old Saxon *hengist, Old Frankish *changisto, Old High German hengist, and Old Norse hestr.
Note A direct descendant of the Old English word does not exist, but it is found in the compound henchman, which literally means “horseman”. As this is highly irregular, I suppose that one might still say Hengest or Hengst with the modern pronunciation of /ˈhɛŋəst/ or /ˈhɛŋst/. This would be consistent with sound changes into Modern English.
Old English Modern English
Name Hors Horse
Pronunciation /hors/ /hɔː(ɹ)s/
Etymology From Proto-Germanic *hrussą “horse” < Proto-Indo-European *ḱers- “to run”. Cognate with Old Frisian hars/hers/hors/ros, Old Saxon hros(s) and ros, Old Frankish *(h)ros, Old High German (h)ros, and Old Norse hross.
Note His name appears as Horsa in extant texts and subsequently in mythological discussions. This is not, however, consistent with Old English and may, in my opinion, represent a transitional form in Anglo-Frisian, which was spoken around the time of his legendary deeds. Final-syllable /ɑ̃/ was lost at the end of this period, if it does, indeed, represent Proto-Germanic <ą>.
