355J: Twins are Split Up and Mother Becomes Town Outcast

I’m looking for a book that I read quite some time ago. The most that I can remember is that the mother was a town outcast, had boy/girl twins, one “died” and was raised by another family. Boy stayed with mom who became town crazy woman outside town. Girl finds out somehow she’s adopted and goes back to figure everything out, and gets involved with a local man. ♥️♥️

264A: Children’s fiction book about adoption

I’m trying to track down a book. It’s a children’s fiction book probably published before the 1980s about a couple who adopts children from different countries. They also have a biological son. One of the children they adopt is from Korea, and there’s a scene that describes their picking him up from the airport. The child only speaks Korean. I read this book as a child in the 80s, but I think it was published before then.
