Romance between a white woman and a Native American man. Set in New England. She was unhappy with her home life (being forced to marry some lout?), and ran away. It was winter; they fell in love and had a child. One section that I recall vividly – she was ill during pregnancy and having difficulty urinating (it was made more romantic than it sounds!) and he brewed herbs and cured her. The title was something like Eagle and Dove or Fox and Rose – one of those Blank and Blank titles. I read this book in the late 1970’s and it was new.
