During the 15th century, the name CYBUL began to spread throughout various regions of Poland, particularly in the central and southern parts of the country. It was often associated with rural communities and agricultural areas, further reinforcing its connection to the cultivation of onions.
In the 16th century, a notable figure bearing the name CYBUL was Marcin Cybulski (1505-1575), a Polish writer and humanist who authored several works on history and philosophy. His surname, "Cybulski," was a variant of "CYBUL" and likely had similar origins.
Another prominent individual with the CYBUL surname was Wojciech Cybulski (1588-1657), a Polish Catholic priest and theologian who served as the rector of the Jagiellonian University in Krakow. He was known for his scholarly works on theology and canon law.
