I finally found them on the USA 1910 census transcribed as Kenyce! Think the Kemp should have an e on the end. Good job she had an unusual first name

Oh and his initial is T not J!
Resident at Ironwood Ward 4 Gogebic? Michigan
Thomas Kempe 33, born England, emigrated 1900, both parents English. Employed as a brakeman on the railroad
Evangeline wife 30 born England both parents English emigrated 1903
Rosedew/Roselew? 1 year 10 months born 1909
Arthur Kempe 23, brother, emigrated 1906, miner in iron mine.
So struck lucky with Thomas's brother Arthur as it will make him easier to identify in the census.
