He married Agnes Tate of Scotland and had several children by this marriage, including my grandfather, Robert Stanley Hoy, born in Sandgate, VT, possibly 9/6/1891, died in Paris, France.Johnand Hamilton Hoy may have been children through a second marriage.Robert Hoy married my grandmother, Thea Alice (or Alice Thea?) Klanderud from Sioux City, IA. They became church missionaries and moved to France where my mother, Madeleine Hoy, was born. Any help is greatly appreciated.
