I am trying to tie back into the Wisconsin area Hennings from my gggrandfather, Julius Henning b: 1857, d: 1926.

What I am pretty confidant in:
He lists Wisconsin as his birthplace on census documentation, he married Julia Elizabeth Junker 6/1879, they had nine children together. He died in 1926.

What I think might be accurate:
Father's name Heinrich or Henry or J.C

Any information or nudges in the right direction are greatly appreciated!
