I am a descendant of John W. Hill. In the 1880 census of Cherokee County, Texas he lists his mother's birth place as "Spain". On the 1860 census in Ray Co., Missouri he lists his own birth place as "KY" (enumerated with the household of Thomas E. R. Ewing).
Recently, I have found something interesting. I have found a possible connection between Fernanda Quintero and Lucretia Hart (from KY), the wife of the statesman, Henry Clay. Lucretia Hart Clay was known to travel to Mexico with her father:
AN OLD TIMER DEAD. James Hill Answers Death's Summons at La Luz.
James Hill, said to be the oldest settler from the states in New Mexico, died at La Luz last week. He was born in Estes county, Kentucky, in 1810, and came to Santa Fe in 1833.
In 1832 he cast his first vote for Andrew Jackson, and during his career in Kentucky he posed as one of the warmest friends of Henry Clay, his wife being a cousin of the great statesman.
During the Mexican war he owned a large hacienda near Chihuahua, Mexico, where he furnished provisions and forage for the American troops camped on the ground. For his loyalty to his country President Juarez imprisoned him and confiscated his estate.
President Lincoln brought pressure to bear which procured his liberation after which he again took up his home in the United States.
