Lucius Plue was located in Roxbury, Delaware Cty., NY. He is living with a family named Montgomery as a farm worker and is 19 yrs old. On the same page of the 1870 census is a Susan Plue 44 working as a domestic servant and on yet another page is a Filbert Plue 13 working as a domestic servant. They can not be located in the 1860 census. Is it possible they were immigrants in the 1860's?
