Country of the Bad Wolfes by James Carlos Blake from the library e-book collection. Unfortunately, I didn't have time to finish (466 pages) before it expired, however, it is available on amazon for $3.82, which is quite a bargain.

Country of the Bad Wolfes by James Carlos Blake
Basing the novel partly on his own ancestors, Blake presents the story of the Wolfe family spanning three generations, centering on two sets of identical twins and the women they love, and ranging from New England to the heart of Mexico before arriving at its powerful climax at the Rio Grande.
Begat by an Irish-English pirate in New Hampshire in 1828, the Wolfe family follows its manifest destiny into war-torn Mexico. There, through the connection of a mysterious American named Edward Little, their fortunes intertwine with those of Porfirio Díaz, who will rule the country for more than thirty years before his overthrow by the Revolution of 1910. In the course of those tumultuous chapters in American and Mexican history, as Díaz grows in power, the Wolfes grow rich and forge a violent history of their own, spawning a fearsome legacy that will pursue them to a climactic reckoning at the Río Grande.
