Half the cemetery is in Vernon Township-Lake County and the other half of the cemetery is in Wheeling Township-Cook County.
The Cook County-Lake county boundary line actually (and rudely) cuts right through the cemetery, east to west.
Ask any ten people in the area where the St Mary’s Catholic Church (Buffalo Grove) cemetery is located and they will tell you “The church and cemetery is in Lake County of course, north of Lake-Cook Road on Buffalo Grove Road in Lake County” And they will boldly emphasize “Lake-Cook Road” as their proof positive. Grandpa and Grandma can be buried in the same exact cemetery plot and in the same cemetery and yet be in two different Illinois counties.
