This is a cross post. Let me me know if it's annoying to see it in other Prewett boards. I'm just trying to reach more people.

The Prewett name of various spelling supposedly originated in the Carmarthen area of Wales. This is according to the House of Names: http://www.houseofnames.com/xq/asp.c/qx/prewitt-coat-arms.ht....

However, I did a search in the British Telecom phone book (http://www.thephonebook.bt.com/publisha.content/en/find/resi...) and there are none of the various "Prewetts", near Carmathen now. On the other hand, there does seem to be a bunch of them in England proper, in an almost straight line from Bristol on the West Coast through Salisbury where Thomas Prewitt, the first Prewitt to reach America came from, to Southampton, on the East Coast of Southern England.

There appear to be only a few Prewetts in Wales now, but no where as many as in Southern England, and maybe the ones in Wales came from Bristol or the like, which is only 79.5 miles as the crow flies, from Carmarthen, as this website points out, http://www.infoplease.com/atlas/calculate-distance.html.

The idea that they came from Carmarthen Wales is research sold by the House of Names Society. I suppose they are good scholars there, but I would like to know their sources.

I would like challenge others to do similar research and improve on my rough data. I know there is a function somewhere in Ancestry.com that will display a map of the UK and the distribution of a surname on it, but I can't find it. My research was perhaps cursory, but I did put in a lot of Prewett spelling variations in the BT lookup system for Carmarthen, and nothing came up.

The site does cover Wales, because when I put in a name like "Singer" I got eight or so entries for the Carmarthen area.
