Family history mentions that Thomas Fisher b. 1829 in Columbiana Co., Ohio, who married Fannie Clark, spent some time in Brownsville, NE, which must be Brownville. His parents Quakers, Joseph Fisher and his second wife Margaret Rawlings, both born in Bucks Co., PA.
From the 1900 Census I know he had a daughter Annie. At that time his niece Annie Carruthers, 35 born in MO in 1865 and grandniece Sophia Carruthers, b. 1887 MO were living with him. He was in Denver in 1900.
