I am also researching the Banker Family of Otsego NY. I have a Martin Banker with his wife, Catherine S. age 32, daughters:Florence 13, Angelaine 8, Lillie 5 and son, Jessie 1, in the 1880 Census. Florence is my husband's great Grandmother;she married Frank J. Brown and lived rest of her life in Otsego Co., NY. Martin is listed as a farmer in Milford Town. Are we researching the same person?Any help appreciated.
