John Emmers married to Nellie(think that is a nickname for Petronella- not sure on the spelling).
I see 5 kids for them on a 1880 Census, Wisconsin.
Mary Emmers was 19.
Theodore Emmers was 18.
Anna Emmers was 8.
Joseph Emmers was 6.
Henry Emmers was 3.

Please contact me if you have any of these Emmers listed in your tree.
Thank you
