The events of Rehoboam’s reign, from start to finish, are recorded ¹  in the Annals of Shemaiah the prophet and of Iddo the seer that include genealogical records.

They made disbursements to all the males three years old and up who were listed in the genealogical records – to all who would enter the Lord’s temple to serve on a daily basis and fulfill their duties as assigned to their divisions. ¹ 

As for the descendants of Aaron, the priests who lived in the outskirts of all their cities, ¹  men were assigned ²  to disburse portions to every male among the priests and to every Levite listed in the genealogical records.
