Hi!
I have a question about English noble second names.
I often meet such names in the books and always get curious what does this part mean:
Fitzwillam
Fitzgerald
Fitzroy
So what does this fitz actually mean?
Is it relative with Scottish patronims Mac or Welsh Ap'?
Or does it stand closely with german Von or general British Of, which adresses to the family seats?
And also for those of you who knows, tell me please the meaning of Irish O's like in second names O'Flynn or O'Donnel.
Thank you!
