Ladan ... Gershon

Translate the names of these men the same as you did in 1 Chronicles 23:7. (See: rc://en/ta/man/translate/translate-names)

descendants of the Gershonites through Ladan, who were heads of families belonging to Ladan the Gershonite

Ladan's descendants were also descendants of Ladan's ancestor Gershon, so the information about them being Gershon's descendants can be left implicit if including it would result in wrong meaning. Alternate translation: "who were leaders of the families of Ladan the Gershonite" (See: rc://en/ta/man/translate/figs-explicit)

Gershonite

A descendant of Gershon. (See: rc://en/ta/man/translate/translate-names)

Jehieli

This is the name of a man. This is the same person as in 1 Chronicles 23:8, but there his name is spelled "Jehiel." (See: rc://en/ta/man/translate/translate-names)
