I have a large amount of Leef (formerly Leu) family history in Saline and Madison Counties in Illinois if anyone needs help.
Leef Township was settled by my great-great-grandfather who came to New Orleans in 1834. Once he earned enough money, he sailed up the Mississippi River to area near Saline & Madison Counties where he bought land, owned a farm, businesses and raised his family.
I have dates on his ancestors to 1677. If anyone has anything further back than that, I'd love to get it too. I can be emailed at:
