The village was first mentioned in 1285 in the document allowing komes Adam to establish a new village Sępnia (contemporary Poręba Wielka), which would lay close to Włosienica.[2] In 1345 a church in a village of Villa Hertmani is mentioned, which was an alleged name of Włosienica, as it could have belonged to a nearby castellan named Herman (1304-1317).[2] Since 1470 to the 20th century the village was endowed to Oświęcim Catholich parish.
