Hi Mary, I don't know if the newspapers are indexed. When I visited Utica, I knew the death dates so I was able to find the obituaries that I needed. When I returned home to Wisconsin, I ordered the 1856 Utica newspaper through the inter library loan and could look at it for 30 days in my local library. I was able to find what the marriage that I was looking for. I wish youmuch luck in your research. Mary Kay
