For what it's worth, the J tribe are apparently resident to Ala Ghiri, according to EE2 and J'olhmyn's bio. Meanwhile, J'dyalani's bio confirms that there was at least one nunh of the J tribe present, and given both J'olhmyn and J'dyalani have "Abah" as their last names, this "J'abah" was that nunh.

According to J'dyalani's bio, J'abah Nunh was killed during the Garlean invasion. No mention after that of whether the J tribe got a new nunh, or are now nunh-less.
