Elkiedee - that's helpful - will note those down, thanks. Have never even heard of Mavis Gallant and Ellen Gilchrist.
Another vote here for: Carol Shields; Margaret Forster (though some of her more recent ones haven't grabbed me as much); Anita Shreve (does longing really well, though can feel a bit samey because it is a recurring theme). Mary Lawson I love(have only read two, look forward to more) and while I liked Barbara Kingsolver's Poisonwood Bible, I couldn't get on with Prodigal Summer.
Digging to America and the Homesick Restaurant are possibly my favourite Ann Tyler, now folk mention them. I have a hard time sometimes remembering a book title if it doesn't immediately relate to the story!
