As I remember, the state of Texcoco in Mexico had several generations of sons succeeding fathers, and then several brothers succeeding brothers.
The last long reigning ruler, Nezahulapilli reigned from 1472 to 1515.
- His son Cacamatzin (1483-1520) reigned from 1516 to 1520. He died during La Noche Triste during the Spanish conquest.
- His half-brother Coanacoch was the next ruler. During Cortes's expedition to Honduras, Coanacoch and Cuauhtemoc of Tenochtitlan were suspected of plotting and hanged from a tree at Campeche in 1524.
- His half-brother Tecocoltzin was the next ruler, dying in 1525.
- His half-brother Fernando de Cortes Ixtlxochhitl II (c. 1500-c. 1550 or died 1531) was the next ruler from 1525. He had already ruled half the kingdom from 1516.
- His half-brother Carlos Ometochtzin was the next ruler, and was burned at the stake for paganism November 30, 1539.
- The next ruler was Antonio Pimentel Tlahiutoltzin who ruled from 1540 to 1546 or 1564. His relationship to previous rulers is not stated.

However, I seem to remember that some sources give more than those five or possibly six as sons of Nezahulapilli who ruled Texcoco.
I think that possibly Stokvis, A.M.H. Manuel d'historie, de genealogie et de chronologie de tous les etats du globe, depuis les temps les plus recules jusqu'a nos jours 1888-1894, tome premier, seconde partie, IIe DIVISION, AMERIQUE, CHAPITRE IX, Mexique might have such a genealogical table. I have been unable to find that chapter in any online version.
