The book I am looking for is about an orphaned girl who is sent out West to live with her cousins and their family. I can’t remember the girl’s name, but the twins were identical twins, and I think their names were Albert and Herbert. I think the book had a red cover, and it was definitely vintage. I read it in the 80’s I think, but my mom loved antique books, so I know it wasn’t a contemporary book. It seemed like it might have been set in the 50’s or earlier. I can’t be sure.
Any help would be greatly appreciated. Thanks so much!
