It was called Frivald, Trencsén, Hungary so I adjusted the location in his profile. The reason why is "Frivaldnádas" is an old variation. These are the variations you may come upon for it.
1902 Trsztyennafrivald, 1907–1913 Frivaldnádas, 1920 Trstená-Frývald, 1927–1948 Frývald-Trstená, 1948 Rajecká Lesná
Frývald: 1773 Frivald, Friwald, 1786 Friwald, Fruwald, Friewald, 1808 Frivald, Friedwald, Friewald, Fříwald, Frýwald, 1863–1900 Frivald
Trstená: 1863, 1877–1882, 1895–1900 Trsztenna, 1873, 1888–1892 Trsztena
Yes, so many but you are right that they are now simply part of Rajecká Lesná in Slovakia now.
All is not lost. I am still looking.
