In 1900, Frank Clement Spurlock was age 16, living in Schuyler, Nebr (Colfax Co) with his siblings and father, Aloisia, age 41, born in Illinois. There were six children in 1900, Frank the second oldest and the youngest only five months old. With no wife listed, it suggets a death of the mother in child-birth.
So far, I cannot find the family in 1860 or 1870 Illinois or Iowa. Perhaps Aloisia was a middle name.
