Millard J. Yost
In 1900 Dawson County, Nebraska, Millard J. born January 1880 in Maryland, is a harness maker, with Daniel 48 and Rachel 47, both born in Pennsylvania. Daniel is a furniture dealer.
Millard cash-claimed a quarter in 32, 7N 48W in 1908 - that's later than most, so it might have been a relinquishment.
He's still a harness maker in 1910 Dawson County, married to Ida M. 28, Nebraska, and they have Kenneth seven months, born in Nebraska.
In 1920 Dawson County Millard and Ida May are farming, with Kenneth L. 10, Lawrence 4, and Verna B. 1.
Millard - 1880-1967 and May 1882-1924 are buried in Sumner cemetery, Dawson County.
So is Kenneth, 1909-1934, and Millard's parents Daniel J. 1851-1936 and Rachel 1854-1964.
