In April of 2012, I posted a review of a recent book about the history of genealogy in the United Kingdom. At one point I wrote: "Perhaps a book on the topic of the history of American genealogy remains to be written."
And apparently it now has. A few weeks ago, the book Family Trees: A History of Genealogy in America by François Weil appeared, and I just discovered that it had. I've bought the Kindle version and I'll bring you a review soon.
