I lived in New England for many years and never heard this word:

""That's the only unbanded chickadee for miles around," says Smith as the pair zips to
an apple tree. "Well, it's not quite true but almost. Listen. The female is calling
'feed me me.' She's growing eggs and he's busily foraging for her. Their nest must be
way out in the dingle," Smith speculates, using a New England colloquialism
for the tangled ravine that drops away behind a neat ranch house whose owners, she
assures a visitor, "know this weird person."

From UK:Where soils are wetter and more basic (calcareous), oak and ash often in
alley or dingle woods occur with alder, birch, wych elm, hazel and hawthorn. Ground flora
is often rich in ancient woodland indicator species. Examples occur particularly in Dudley
with dingle woods e.g. Cotwall End Dingle,
Wollescote and Hodgehole Dingles.

from M-W:

Main Entry: din.gle
Pronunciation: 'di[ng]-g&l
Function: noun
Etymology: Middle English, deep hollow
Date: 13th century
: a small wooded valley : DELL

I have heard it, not in New England, but in the Lord of the Rings, especially around the Tom Bombadil section, if I'm remembering correctly.

There is a Dingle Peninsular on Ireland's wild west coast. The little bay on the peninsular is where the Lt and woman meet in the movie of novel "The French Lieutenant's Woman."
However in next scene the beach has the Cliff's of Mohr in background which are further up the coast, north of Limerick. Movie magic.

The Dingle beach is beautiful, small,and you have to scramble down a steep rocky path to get to it. The surf has a nice left break which my son's surfed in 1971. Lost a full wet suit there...if anyone finds it washed up on the sands, keep it. They've outgrown it!

never heard of the dingley dell?
( it is where the faerie folk live)

And we speak here, in Virginia, of "dingle berries" that stick to your clothes. Dingle berries are also sometimes reffered to here as "sheep burrs."

or of course the dingley dell is also the home of Mr. Wardle and his family, and the scene of Tupman’s love adventure with Miss Rachel. (Dickens: Pickwick Papers.)

Might wanna be careful with this term in other parts of the country, Dub. It can mean something quite else and much less acceptable in mixed company.

So, you can tell which part of the country an Indian is from by the shock he does or does not manifest when you ask, "Do your dingle berries stick to your clothes?"

Cross-thread reference...sortof...to Blackfeet/Whitefeet Indians
