I am looking for any information in regards to a man that went by the name Herman Boreman or Siegfried Alvarez. He lives in San Francisco in the 1970's. He has an older brother named Walter Alvarez who still lives in Mexico and three other brothers who live in California.

I know that he was born in Morelia, Michoacan - mexico I believe in the early 1930's.

Any information in regards to this man, I would greatly appreciate it.
