First I have a question about surnames. Do correct me if I'm wrong, but as I understand it, the prefixes Mc-, Mac-, and Fitz- indicate "son of," and o'- indicates "grandson of" in Ireland, Scotland, and England. Does this type of thing have a name? Is/was this used in other countries and languages (I know Iceland does this with daughters as well as sons)? Can you provide me with examples, or point me to some wonderful website that addresses this?
Second, do you have any suggestions for how one might go about coming up with plausible-sounding names for both people and places when writing fantasy stories? I understand that the general concept would involve examining real cultures and taking a look at the names and place names they use, but I'd like to go into a fair bit of detail in coming up with these... and by that I mean putting in more effort than just glancing at a map of, say, Iceland and then attempting to spit out "Icelandic sounding" place names. Are there, for instance, patterns you know of that I might look out for? Perhaps resources that could advise me in this matter better?
Thanks in advance for any help you may be able to offer!
