[Facts] Re: Dallin, and other "valley" names
in reply to a message by thegriffon
There is Proto-Germanic *dalą or *dalaz meaning "valley, dale", the descendants of which you can see here:

There are some recently created names with its Icelandic descendant in Iceland, which you can see here:

It appears that in older times, none of the descendants of Proto-Germanic *dalą or *dalaz were used in given names. At least, Altdeutsches Namenbuch by Ernst Förstemann (which contains nearly all West Germanic given names used in the medieval period) makes no mention of it. It does list the element DALA on page 399, but indicates that it should be related to the Anglo-Saxon adjective deall meaning "clarus, superbus" in Latin.
