[IIL] 'Old timey' songs like these [linked in post] [WEWIL]?

I found these couple of songs in some meme-style videos and I felt that the music was very emotional and had this mix of beautiful sadness that I haven't really heard much of in the music I'm familiar with. I'd really love to find more music like this! Can you lemme know what genre this is and where I could look up more music like this?
