I was reading in Wikipedia that the origins of European surnames can be classified into categories like patronymics, occupational, toponymics and nicknames. If this classification is old or incomplete please do correct me --- I know quite little about linguistics.
What I am wondering is whether any kind of study has been conducted on the geographic and cultural distribution of these different origins: for example, it seems to me (qualitatively --- not sure at all if it is actually the case) that medieval Anglo-Saxon names tend to be more patronymic-focused, while medieval Italian names are more toponymic-focused.
This example is about medieval surnames but I am interested in modern surnames as well, I generally would like to know more about whether there are measurable "cultural trends" in (sur-)naming conventions.
The Wikipedia article extensivey quotes "A Dictionary of Surnames" by Hanks, unfortunately I could not find a copy but it seems from what I have seen that it does not contain this kind of analysis and it is more of a compendium of origins and names. I have done a few Google Scholar searches but cannot seem to find any article doing the kind of broad analysis I am interested in.
