Chopin was really Frenchmain
From The Fryderyk Chopin Institute:
250 years ago Mikołaj Chopin, Fryderyk Chopin’s father was born.
Mikołaj was born in the French town of Marainville to François Chopin, a trustee and wheelwright, and Marguerite née Dauphin. Despite his father’s poor financial situation, he graduated from the secondary school in Tantimont, which prepared young people to become priests and teachers. Because of his position as a trustee from 1776 to 1785, François Chopin was in contact with Adam Jan Weydlich, an administrator of the chateau at Marainville, owned by Count Michał Jan Pac.
Weydlich’s wife, Françoise Nicole Schelling, intelligent and educated, taught the teenage Mikołaj savoir-vivre, German, literary French, calligraphy, accounting and music. After the death of the castle’s owner, Count Pac, the Weydlichs decided to return to Poland. Mikołaj, probably having in mind the deteriorating financial situation of the family and growing conflicts in France, decided to leave with them and in the autumn of 1787 left his homeland forever.
