That cemetery isn't old enough. Cornelius died before 5 feb 1877 , so 1876 should be the year. Ann has paper saying widowed.
Thanks for directions. With 2010 map software it is easy to see. That's place I haven't been too.

I did have right phat map saved. I'm not good at reading that stuff. I figured I'd get dad to pin point it someday. They owned that land till after April 1882. I got land record dated that. I don't really understand why or where they moved to at that other county. They had son John that bought 80 acres in 1869 in Webster Co. but I don't think he move here then. Of course 1890 census got burned up. 1900 all of them was in Webster Co.

1876 is really old headstone around here < this part Missouri > if there was ever one. Couple Rocks and cemetery plots map record my be what I need.
