This document is about Joiada (son of Eliashib). For other homonyms, please refer to the Joiada document.
He was the son of Eliashib, the high priest during the time of Nehemiah (governor). In Nehemiah 13, he is also mentioned as a grandson.
In Hebrew genealogies, it is common for a grandchild to be directly referred to as a child if the parent died early or did not achieve anything particularly noteworthy. Therefore, it is likely that he was indeed Eliashib's grandson.
