Ruth Koski, orphan, is found in the 1920 census of Brookfield, Linn Co, MO in my great granduncle's home. My great granduncle and his family are:
Leverette Humphrey, head, married, male, 56, born in IA
Lillie Humphrey, wife, married, female, 45, born in WI
Lester Humphrey, son, single, male, 22, born in IA
Henry Simmons, father-in-law, widower, male, 77, born in OH
Ruth Koski, orphan, single, female, 6, born in MO
I do not know who Ruth Koski is or why she is living with this family. Can anyone help solve this puzzle?
