Henry T. Cook is a native Californian and the son of one of the pioneer settlers of the state. His father, John J. Cook, was born in Michigan, and his mother, who was Miss Mary Ann Turley before her marriage, was a native of Canada. Their were five children born to them, Henry T. first seeing the light of day one year after the emigration of the family to California. The father died at the family home in San Bernardino county when fifty-six years old, and the mother, who later made her home with this son, lived to be seventy-seven years of age. The birth of Henry T. Cook occurred February 9, 1863, in San Bernardino, and his education was received through the medium of the public schools of that city and Los Angeles county. After ranching in the San Joaquin valley for one year he removed to Hollister, where he remained for three years, and from there in 1876 moved to the Santa Clara valley of Southern California and purchased the ranch which is now his home. It comprises one hundred and twenty acres of as fertile land as there is in the valley, nad of thi shs has ninety acres of beans, the rest being hay land. He has more recently planted sixty acres to walnuts, which will soon yield him a handsome income.
Mr Cook’s marriage united him with Sarah E. Wilkinson, who was born in Illinois, and to them have been born two children, both of whom are now maried. William H. married Winnifred Huff, and Walter A. married Irene Stockton, and to them one child has been born. Mr. Cook is a member of the Odd Fellows Lodge at Santa Pula, and takes a lively interest in political matters, being a member of the Republican county central committee. He is a hale fellow well mt, highly respected and esteemed and in every way a successful businessman.
