Kirio Hikifune couldn't have been part of them. She joined the Gotei waaay after its formation. Its impossible to know who where the remaining seven. I would assume one from each of the great noble houses (even the shiba) Judging by Ginrei's age i "would" say he was part of it. But he didn't join the Gotei until after Shunsui and Jushiro. Since we have only seen a handful of "old" characters its impossible to say.
