When I lived in Madrid, Spain in 1979, I met a lady named Isabel Bottex. She was from Argentina. She was a singer and either dated or married Xavier Cugat, but was no longer with him. She had two sons, Alex and Willie. I used to write to her in the 90's and she came to see me for a few weeks, but I lost track of her. Somewhere, I still have her address. I can look for it if you think this might be the same person. She spoke Spanish, Portuguese and English.
