My last name is Vaughn with the variation Vaughan.  In welsh it means
"little" but I'm trying to find out if there is an animal associated
with the family name.  Is there a specific animal associated the name
Vaughn, Vaughan in either it's Irish or Welsh forms?

jazzed,
I find the old gaelic names and their meanings fascinating.  "Vaughn"
is an anglicized (as I'm sure you know) version of MacMahon which
means "Bear" or "Divine Bearcub".

I posted two links below; the second link has a photogrpagh of
pre-Christian stone carved bears.

MacMahon is one of the best-known and most distinguished names in
Ireland. In Irish Mac Mathghamha, or in ultra-modern spelling
MacMahuna, it is said to be derived from the Irish word for a bear. .
. .
This surname, O Mochain in Irish and properly Mohan in English, spread
in to Munster, where it was usually anglicized Vaughan. Though Vaughan
is, of course, a common Welsh name most of our Irish Vaughans are in
fact of this Gaelic stock.

The Divine Bear Cub 
Math-ghamain properly meant the calf of the bear, or bearcub. Yet this
word signifies only ?bear? today.
Mathghamhna, the genitive singular of Mathghamhain, is today spelled
?Mahon,? and this is the second part of the family name MacMahon,
which is written in Irish, Mac Mathghamhna, and which means ?the son
of the bear.?
