Here are the relationships in the Holland family. The confusion for some readers is the fact there are two Hackberry Hollands. So I’ll try to clear up what I can.
The patriarch of the family is Son Holland, who escaped from a Louisiana chain gang in 1835 and fled to Texas and fought at the Battle of San Jacinto for Texas’ independence from Mexico.
His son was Sam Morgan Holland, who was a Confederate soldier, a trail drover, a drunkard, a gunman who killed nine men, and finally a Baptist saddle preacher. He was also the lover of the Cimarron Rose, a beautiful outlaw queen in Indian Territory.
His son was Hackberry Holland the older, who was a Texas Ranger and frontier lawman who put John Wesley Hardin in jail.
The grandson of Hackberry was named for his grandfather and was a Navy corpsman at the Chosin Reservoir during the Korean war, a POW in a hellish prison in No Name Valley, a lawyer for the American Civil Liberties Union, and a sheriff on the Texas-Mexican border.
Billy Bob Holland, his cousin, was also a Texas Ranger and an attorney. Billy Bob is the great-grandson of Sam Morgan Holland.
Ismael Holland is the son of Hackberry Holland the older and was among Pershing’s punitive expedition into Mexico in 1916 and a participant in the Battle of the Somme.
Weldon Holland is the grandson of Hackberry Holland, and was in the Ardennes during WW 2. He narrates Wayfaring Stranger.
Aaron Holland Broussard is also the grandson of Hackberry Holland the older, and is the narrator of The Jealous Kind. The latter completes a trilogy that includes Wayfaring Stranger and House of the Rising Sun.
