The personal name Chemer derives from the toponym Chemeryntsi, which is mentioned in Lviv region in 1383 as Ciemierzynce, and in 1469 as Czemermcze. According to research by M. Hudash and M. Demchuk, the personal name Chemer may originate from the appellative "chemera," meaning 'headache'. However, a more probable version suggests that the ancient Volyn anthroponym Chemery comes from the appellative "chemer," which means 'poisonous plant'. A known record of the anthroponym dates back to 1404: "we... Hodko Chemery - the village of Medyka," as well as a patronymic from 1399: Pan Hodko Chemєrevych - the city of Lviv.
