Some sources state that the village was first mentioned in a Latin document of Diocese of Wrocław called Liber fundationis episcopatus Vratislaviensis from around 1305 as item Rudgeri villa, however it is very unlikely and disputed.[a] Far more likely it was later mentioned in 1434 as Lhoty and in 1450 as Rozkowu Lhotu. Later up the Morávka river the sister settlement of Vyšní Lhoty was established. They were then both mentioned in 1584 as Dolny neb Spodny Lhota (Nižní Lhoty) and Hornÿ Lhota (Vyšní Lhoty).
^This leaves the question what happened to Rudgeri villa, as it indeed lay somewhere in the vicinity but is now considered lost. It was probably absorbed by another nearby village, but not necessarily by Nižní Lhoty.
