In Breaking Bad, as far as I understood, Gustavo Fring never really had a family of his own. It is logical from one perspective not to have anyone valuable to you when doing business of the sort. However, following Gustavo's ability to keep his enemies close and display himself as a low profile business owner with normal life, I start to think that he should have had a family. Have there been any hints about his personal life, any ideas, thoughts or assumptions?
This is taken directly from the Breaking Bad Wiki, which is usually pretty spot on:
Gus also claims to have children, though they have never been seen nor anybody else in his family life has been revealed.
