I know you posted your question 10 years ago but we are doing a family tree search for my wife's 2nd great grandfather named Florentino C Morago, later known Frank Cota Morago(Moraga). We know he was born in 1879 in Santa Barbara, California, lived in Azusa, El Monte, Pasadena, Escondido then finally died in San Bernardino, California. He listed his Mother's maiden name as Cota and his Father's as either Morago or Moraga. He also listed a Carmel Morago as a next of kin. The family was always told they are Native Americans from a California tribe that I haven't been able to identify yet. There even was a payout at sometime to Florentino/Frank's children. I'm hoping that you might have more information that could help us, and I might have some information that could help you.
