Thanks everyone for your help. I have been looking for my great grandmother Mary Miller's family. She married a David Hott in 1874. I received an e-mail that William G Miller and Dorcas Catherine Duckworth had a child Mary Louisa Miller, but not sure that this is my great grandmother. Although, it seems that the census may be pointing to that. I am sending for her death certificate, so hoping that her parents are on there. thanks Carol
