I have looked for the deaths of both of them, for years. Alice was remarried to John T. Kelly in 1872. Alice and Kelly were divorced in 1883, and Alice disappeared. The last time I found her was the 1880 census with Kelly. Then the messy divorce in the 1883 New York Times. Rumour has it that Hotchkiss died in 1878 (according to NY times) but I didn't find it.
