Having just moved into this area I was interested to learn that
the town of Arundel got its name from the French for swallow, hirondelle,
that came over with the Normans. I thought it would have had something to do with the River Arun on which it sits. Can anyone confirm the swallow connection?
The Oxford Names Companion gives the name in the Doomsday Book as 'Harundel' meaning 'valley where the plant horehound grows', from the Old English 'hârhûne' + 'dell', with the name of the river being a 'back formation' from the name of the settlement.
On top of that JNO, the battle of Hastings was fought in October and swallows are summer visitors, so that makes it even less likely they came over with the Normans.
The names of rivers and trees are remarkably invariant ( In English anyway ) and I was taught in the sixties when I visited that Arun was a variant of Avon ( Celtic for river - using Celtic to describe the language ancient britons spoke before the Romans came )
and -dle was the hill
The thing about Sussex - is that after 1066 it was the only county to reorganised in an admin sense. The anglo-saxon admin was scrapped and the land was re-organised into North-South strips called 'rapes' were nt they ? It represents the importance of Sussex as a way from gay paree to London. It would then make sense for a new Norman fief holder to say Arundel - oh it must come from Hirondelle - oo look there is one !
