We can see Kira's birthmark here http://bato.to/read/_/155232/jojos-bizarre-adventure-part-8-jojolion_ch18_by_hi-wa-mata-noboru/4

Kira IS a Joestar, it is said by Kyo Nijimura (his sister), and he is in the family tree, being the son of Holy.

By the way, the joestar birthmark is shown only when Araki wants to show it, as it is supposed to be behind and not on the front. Since we already know that Kira is a Joestar, there was no use to show the birthmark to us.
