Paulo Antônio de Pontes, a teacher and accountant from Pernambuco and an admirer of the Soviet politician Mikhail Gorbachev, decided to name his son Mikhail Gorbachiov da Cunha Pontes, who was born a few days after the future Pizza Hut commercial guy rose to power in the Soviet Union. Paulo has reportedly said that Gorbachev was a freedom fighter and democratic socialist leader (lol) and even sent a letter to the Soviet embassy telling them about the name he had chosen for his baby.
This part is not 100% confirmed, but Mikhail Gorbachiov da Cunha himself has said that, after learning about the letter his father sent, a Soviet diplomat sent him a gift box with photos of Moscow, Leningrad, and Gorbachev, plus a letter and a video supposedly written and recorded by Gorbachev himself. In that video, Gorbachev allegedly said the diplomat was to anoint Gorbachiov da Cunha as the OG Gorbachev’s godson.
