I pronounce
Fionn as "fin." Great name.
I've never seen or heard of
Zoticus before. But I would guess, "ZOE-ti-cus." Interesting name. More information, please.
I prefer
Llyr. I really like this, but it's not very practical. (This from a woman who would name her American dd
Niamh or
Aoife, so take with grain of salt.)
