With the news of the newest version of Scrivener 2.6 for the Mac I have also found a site with several collections of names for the name generator. Provided by DL Thurston is comes in the form of several CSV files you can import. The files all work on the PC version of Scrivener (I have tested a few) and there are suggestions that they should work on the Mac version (not tested yet). The names are here: Windows Name Gen Files. The rest of DL’s site is of interest to science fiction fans – do have a look.
The names mainly cover periods of US history but there are some English period names (from the Census records) and some other bits including biblical names. As the blog post says some of these sets seem ready made for fantasy novels.
If you know of any other similar resource, please let me know.
