Morning Julie, No I do not know when the cemetery was started. My educated guess would be probably 1840-1850 maybe earlierbut not before Will became a separate county(about mid 1830's). There was also another cemetery on the west side of Joliet which no longer exists. Within the past 4 years, there was an article in the Herlad News about a woman finding a tombstone from that cemetery. As I recall, it had a burial date in 1830's.Location of that cemetery was around current West Jefferson Street and Reed St which now has a strip shopping mall. Kathy
