Hendon Family History

English: habitational name from one or more places so named such as Hendon (Middlesex), Henden in Sundridge, Handen in Aldington, a lost Henden in Woodchurch (all Kent), a lost Hendon in Hellingly (Sussex), and Hendon in Luffincott (Devon).

There is also a place of this name in Durham, but this is probably not a source of the modern surname.

The Kent and Sussex placenames derive from Old English hēan, dative form of hēah ‘high’ + denn ‘pasture’, while the other placenames come from Old English hēan + dūn ‘hill’.
