In UT, it is stated somewhere in the tale of Tar-Aldarion and Erendis that rule is passed on to the oldest child (boy or girl) of the previous king, and to the oldest next of kin from there. So probably Isildur himself, then his oldest child would inherit the throne.
I like Eldacar's story. That was a tumultuous time in Gondor. Fighting his cousin who becomes king, who kills his son, who he eventually kills and his family flees to Umbar. Not only that he himself being a controversial king since his mom was not Dunedain and during that time most of Gondor's best blood was lost.
