Fernandez, who died in August aged 99, emigrated to Mexico in 1949 before he became the chairman of Grupo Modelo and played a key role in turning Corona beer into a global hit.
Having grown up in poverty as one of 13 children, Fernandez never forgot his roots. In his will he reportedly left over 200 million euros ($212 million) to his many nieces and nephews in the area, and paid for a new cultural center as well as making a large donation to a local non-profit foundation which employs some 300 local people.
In fact, besides Fernandez there have been several wealthy benefactors who decided to share their estate in completely unconventional ways after their death; here are some more of them.
Leona Helmsley
Leona Helmsley was a flamboyant American businesswoman who became president of the Helmsley hotel chain in 1980, following her marriage to New York real estate investor and broker Harry B. Helmsley. Before his marriage, Harry Helmsley had accumulated an estimated $5 billion in real estate, including the Empire State Building.
However, in 1989 Helmsley was convicted of income tax evasion and fraud and spent 18 months in a federal prison. During the trial, reports about her bad behavior to staff earned her the nickname "Queen of Mean." She was also famously reported as saying, "Only the little people pay taxes."
Two of Helmsley's grandchildren received $10 million in the will, provided they visit their father's grave every year. However, two other grandchildren got nothing. Most controversially, Helmsley left a $12 million trust fund to her Maltese dog Trouble, which was later reduced by a judge to $2 million on the grounds that it was excessive.
George Bernard Shaw
The Anglo-Irish author and playwright George Bernard Shaw, known for such works as "Pygmalion" and "Man and Superman," also promoted reform of the English alphabet.
Shaw considered the English alphabet, with its irregular spellings, as inadequate for writing English. From 1926 he served on the BBC's Advisory Committee on Spoken English, where he associated with several exponents of phonetic writing.
He also said that his play Androcles and the Lion should be printed in the winning alphabet. The competition was won by Ronald Kingsley Read, but apart from Androcles and the Lion few works have been published in the new alphabet.
Charles Vance Miller
Charles Vance Millar was a Toronto-based lawyer and financier who loved practical jokes. One of his favorite tricks was to leave money on a sidewalk, then hide and watch passers-by pocket the cash.
Millar died in 1926, aged 73, without any descendants. In the preamble to the will, Millar said that he took the opportunity to continue having some fun, beyond the grave.
"This will is necessarily uncommon and capricious because I have no dependents or near relations and no duty rests upon me to leave any property at my death and what I do leave is proof of my folly in gathering and retaining more than I required in my lifetime."
The final clause caused the most consternation in Toronto. It became known as the "Stork Derby" and stipulated that the rest of his estate be given to the Toronto mother who managed to have the most children in the nine years since his death.
After a string of legal battles in which the legitimacy of various claims was contested, in the end CAD$570,000 (CAD$9.7 million or $7.2 million today) was shared between four mothers, who had each given birth to nine children in the Toronto area.
Rolf Eden
Although he hasn't died, the will of 86-year-old German businessman Rolf Eden has already gained attention for its unusual contents.
Eden is a former Berlin nightclub impresario known for being a playboy, and he has seven children by seven different women.
In his will, Eden has stated that should he die while having sex, the woman involved will receive a large sum of money. Before the advent of the Euro, Eden promised 500,000 German marks, and has now fixed the sum at €250,000 ($265,000).
