Ok, so I have been doing some searching and it appears so far that Pierce is correct. I found the tombstone for Luther Snow at find a grave. He is buried at Brookside Cemetery in Franklin Forks, Susquehanna, PA. He died 30 Oct. 1878, his stone says H/O of Anna Eliza Fisk. In 1880, I found Eliza living with her brother Asa Fisk Jr and his 2nd wife Caroline, in Conklin, Broome, New York.
I have seen some family trees that show she died in 1882 in Minnesota but I haven't found anything that supports that or places her in Minnesota, so far. That doesn't mean it isn't true I just haven't found anything myself.
