Interesting sites, Bill. Thanks for posting them. I can't find my mother's maiden name, Degnan, anywhere. Her father's parents came to the US from Ireland, so I thought I would find it. It's probably a variation of Deignan, which is in there:

An important Leitrim-Roscommon family who moved to Cavan, Longford and Westmeath and where the name is often spelt Dignam

My 'maiden' name, Cunningham is a place related name:

(origin: Local) A district in Ayrshire, Scotland. The name signifies the dwelling of the chief or king, from the Saxon, cyning, Dutch, koning, a leader or chief, and ham, a house or town.

My current last name, Dale, was addressed above, but I like this meaning in the site you posted:

...a bushy vale; low ground, with ground ascending around it.

So I'm a descendent of the Leitrim-Roscommon family in a dwelling of a chief or king, nestled in a vale of low ground with ground ascending around me ;-)
