Ok, I'm ready to accept now that Yanamanamanda is an Indian name, though I still don't know exactly what it means. I guess I talk a lot of rubbish, but I can't say that I'm sorry. I just couldn't make sense of the first part, 'Yana', but now I realize it could well be the Sanskrit word 'yajna' meaning sacrifice. This sounds pretty much like 'yana', so it's a perfectly logical simplification of a surname. There are many words that start with 'Yajna', and a few that start with 'yajnaman': a temple's patron is called yajnamana, "sacrificer", (not in my dict. but looks reasonable), and 'yajnamanman' means "ready to sacrifice".
