Ethnicity & Alliteration

Anecdotally, I’ve noticed that people of [name]Indian[/name] and of Armenian descent tend to have alliterative initials more commonly than other people do. Is this indicative of a larger trend or just random? [name]Do[/name] any ethnicities/languages/cultures favor alliterative initials?

OOH, this sounds a very intelligent post, Mnemosyne! Can you elucidate a bit more, please?
