My g-g-grandfather was a man named Cornelius
Groesbeck. He died in Jo Daviess Co., Illinois
in 1846. Jo Daviess Co. is the very northwest
corner of Illinois - just across the river from
Dubuque. Cornelius had a son James Groesbeck.
I know that James was still alive in 1893 when
his mother Elizabeth Denure Groesbeck died.
If there is a 'fit' here I'd be happy to share
