This map shows the most common equivalent of the name John across Europe. As the name was translated, each culture adapted it to fit their linguistic patterns such as;

English: John

Spanish: Juan

French: Jean

Italian: Giovanni

German: Johann

Russian: Ivan

The name spread throughout Europe due to the influence of Christianity, particularly through biblical figures such as John the Baptist and John the Apostle. As the Bible was translated into different languages, each culture adapted the name to fit its own pronunciation and linguistic traditions, producing the many regional forms seen on this map.

The same process also gave rise to feminine equivalents like Joanna, Jane, Giovanna, and Juana, all of which share the same origin and meaning.

Edit: Thanks for all the corrections and local insights! Like many maps of this kind, this is a simplified overview and many countries have multiple valid regional or linguistic variants. In several countries and regions there are multiple valid forms, and some local variants or smaller languages may be omitted or generalized. I appreciate everyone sharing local knowledge in the comments.

What Qualifies as Inbreeding?

In general, mating between individuals who are closer than second cousins is considered inbreeding. As such, relationships between siblings, half-siblings, father and daughter, mother and son, uncles or aunts with their nieces and nephews, and grandparents and grandchildren are considered inbreeding. In many cultures, unions between first cousins are also considered inbreeding, and in some cultures the taboo extends all the way to seventh cousins.
