I’m quite happy to see my whole extended family taking a serious interest in history. In fact we had a family reunion yesterday and it was held at a “Farm heritage park and museum” that my grandmother has been involved with for years.
I hope you know about FReeper Larry Schweikart’s A Patriot’s History of the United States. You and your family would probably like it.
