What is "sielecki"

Sielecki (females are named Sielecka) is a Polish surname, also of one of the noble ( szlachta) families. It is derived from the village of Sielec, of which many exist with that name in Poland, Ukraine and Belarus.

As is typical with Polish surnames, if noble families exist with the same family name but are not related to each other, a coat of arms was assigned to them in order to differentiate between each other. A person with the surname Sielecki does therefore not necessarily have to be related to each other or even be noble.

The Sielecki family from Sielec, Drohobych Raion were Greek catholic as well as Roman catholic, while there are other Sieleckis who are Jewish from places such as Lithuania and Belarus, many of whom live in Argentina and South America today.
