Here’s a sampling of the helpful tips you’ll get in the Illinois guide:
- Nomadic Paleo-Indians and their descendants explored what’s now Illinois long before the first Europeans, Frenchmen Jacques Marquette and Louis Jolliet, arrived in 1673. Twenty-six years later, French priests founded a settlement at Cahokia, and in 1717, the area became part of French Louisiana.
- The Illinois Regional Archives Depository (IRAD) system, part of the state archives, will point you to vital records housed at seven state universities.
- The US government counted Illinois residents every 10 years starting in 1800. That initial census was lost, and only Randolph County remains from the 1810 enumeration.
