Um wrong? FFII = Orphans. Every main character that fights in the final battle. That makes it at least 5 out of 13, which is a solid 38%. (More than a freaking third of these games).

Also, FFVII, Clouds and Tifa's parents where killed, RedXIII's entire sideplot was about his dead father. Marlene was orphaned because her father had too much "blood on his hands" or whatever that Dyne sideplot was about. Hell, Sephiroth was even Orphaned from his parents.

smurf, FFIX Vivi has no parents whatsoever (unless you count Kuja lulz) and I can't help but feel Quina reproduces asexually.

There is no way you could deny that a freaking LOT of Orphans have been used in this series.
