Patronymic

A patronymic is a personal name based on the name of one's father.

For example in Russian a man named Ivan (John) whose father's name is Nikolai would be known as Ivan Nikolaevich or "Ivan, son of Nikolai" (Nikolaevich as patronymic). In women the ending is -evna or -ovna.

In Scandinavian languages, the patronymic was formed by using the ending -son (later -sen in Danish) to indicate "son of", and -dotter (Icelandic -dóttir) for "daughter of". This name was generally used as a last name although a third name, a so-called byname based on location or personal charateristic was often added to disambiguate people.

In Dutch, the ending -s, for son, was used for sons and often for daughters, too. The Dutch sometimes used -docter or -dr for daughters.

In many areas patronymics predate the use of surnames. They are still used in Iceland - along with the less common matronymics - where few people have surnames. Many English, Welsh and Scandinavian surnames originate from patronymics, eg. Wilson (son of William), Powell (ap Howell), Johansson (son of Johan), Eriksen (son of Erik).
