Stephen Birmingham wrote a lot of books on the Jewish Emigration to America experience, the Irish and German emigration experience and lot of non fiction books on what happened to society when they got here. Social strata books. Back in the 80's I think it was he wrote a series of books of fiction on this too and I am stunned to see you can't even get some of them any more, they don't even list them, several sagas of families which were absolutely wonderful. I think one was called The Emigrants.
I THINK I still have them, all the fiction ones, somewhere on the shelves, if one could even open up the old creaky pages (surely the '80's were not that long ago) but his non fiction books are more well known and have apparently taken over. But they were good books. Really good reads. Very Chaim Potok in style, and he's also a very good writer.
They actually inspired a lot of my own interest in the emigration to America sagas. Those were tough people. When we were considering a Bookfest once, in the Midwest, we wrote Birmingham, he'd be in his mid 80s today, and who said he'd come if his expenses were paid but of course we could not afford to pay him, (and it wasn't particularly nearby)...I always wished we had had that pleasure. His fiction sagas do not let one go.
