I see a George F b Aug 1876 married to Emma E born Sept. 1874 and son Thomas F born June 1899 living in Tremont from the 1900 census.
Keeping this in mind I checked the 1890 census and I see Minnig (could be a variation). The age of George in this family is close:
MINNIG Regina, Francis 42 Miner, Justina, Charles 18 Laborer, George 14 Laborer, Thomas 10,
Harry 5, William 1, Katie, Ida, Flote
When I check the 1880 census, Francis & Justina are the husband and wife. Regina must be the mother of Francis. She died in 1892 and is buried in the Reformed cemetery
