What You’re Seeing is a Welsh Place Name Not a Keyboard AccidentFebruary 26th, 2011
The first time I stumbled across an ancestor who was born in LngtwgDyfrynWysg I decided some older relation had given up trying to type in the correct name and this was just gobbledegook.
Luckily I tried taking pieces of the place name and searching for them- Dyfryn then Dyfryn Wysg which got me to Llangatwg Dyffryn Wysg (which is listed in some English gazeteers as Llangattock-Nigh-Usk)
Don’t assume the place name is completely made up. It might be just a letter or two off.
