Hi Cindy
In the 1910 US Census there is this family:
Rockbridge, Richland, Wisconsin
John H SMITH, Head, 51; born Ohio as were his parents; farmer
Ida SMITH, Wife, 49; married 33 years; 5 children; born Ire, English; mother born Scot, English; emigrated 1871
Christie McGIFFIN, Daughter, 28; married 1 year; 1 child; born Wisconsin
Frank McGIFFIN, Grandson, 6/12; born Wisconsin
Could this be them?
