The mother died when the girl child was about three. John H. Fisher remarried and had two children by his second wife, who also raised the girl from the first wife. Of these two children by his second wife, one died in infancy and the other a son died at age 19. This son was also a John H. not John J.. He was born in 1888 and died in 1908. He never was married and noted as single on his death record. So I do not think these are the one in the same person that you are looking for.
