Dunn in chicago/Ill / 1800s
I'm trying to track a family of distant cousins. Brothers Patrick and Mike Dunn (circa 1870s) in Chicago. Pat Dunn owned a bar in Chicago and Mike Dunn was a teamster. They were born in Ireland. Possible relation called Kate Dunn (b.1862 in Ireland) (in Chicago 1880 census).
They are related to a Carline Dunn form Queens County, Ireland
