Hi.

This looks like you are doing a mechanical edit (starting with cities in A-) to add names in latin, with more changesets to come.  Not sure this is a good idea.
Another useful reading here before proceeding further: https://wiki.openstreetmap.org/wiki/Automated_Edits_code_of_conduct

Same concern as @mcliquid: unless the book is in the public domain or has been published under a compatible licence, it is not allowed to import the names you found there into OSM.

Also, the Belgian city of Aalst was already translated as "Alostum", and you changed it into Halosta.  This is probably very futile, latin was extinct long before the town was founded.
