Two American brothers Charles and Hunter ANDERSON settled in Mexico - first Tamico, later Mexico City in early 1900. They were newspaper publishers. Hunter marries Charles' wife niece Altagracia BUENO - she was born Leon Aldamas(?).
Her parents are listed on her US SS application as Ignacio J. Bueno and Esther Casca. I am not sure of Charles' wife's name - Estella is her first.
Another nephew John Hanna also lived in Mexico City and married Maria Luisa daughter of Mannuel GARDENAS, Coah, Mexico. Their family still lives in Mexico City.
