Hi Jason

On the US 1880 census for Kansas, Marshall County, Blue Rapids.
Emmingham,
William, 48, born England, parents born Eng. Farmer
Louise, 38, born NY, parents b NY
Cornelia, dtr, 8, born Kansas
Catherine, dtr, 6, born Kansas
Charles, son, 5, born Kansas
William S 7 months, born KansasCyner???, son 3, born NY
Also in the household
Vose, William C, BIL, 50, b NY Works on Farm
Harriet 48, SIL 48, b NY
As William, on later census states that his father was born in England and his mother in New York, I strongly feel that this is him but you must decide for yourself.
