Which have alternative spellings  or have changed completely

The list also includes places with different Welsh/English names, the Welsh  version will usually be found in the first column, alternative 1
Use your browser's Find facility to search for particular names which may be in the second column, alternative 2

The list doesn't include minor spelling variations, or a single L for LL or those caused by use of the English K for C. or V for F.
Although some of that ilk are included because they more accurately  indicate the origin of the name
