From http://www.houseofnames.com/evans-coat-of-arms Evans was "first founded in Herefordshire from very ancient times...before the Norman Conquest and the arrival of Duke William in Hastings in 1066.
This is the Evans family crest which I like very much!
In my research about the name Evans, I found a piece about its connection to the famous King Arthur. From the same link as above, it says that "Writers and historians have long been divided ... on the truth of Arthur, the great Welsh king of Britain. Although many now think that there is some truth underlying the many varied accounts, the hard facts surrounding Arthur's reign are almost completely obscured in a mist of myths and legends."
So...on my mother's side, there is speculation that I may be the great granddaughter of a Scottish Lord (albeit born on the wrong side of the blanket) and could it possibly be that my new husband comes from the family of King Arthur?
You may call me Lady Evans now. Curtsies graciously accepted.
