Possibly Peter Cornia and his wife's stepmother, Cordelia Hotchkiss Carter, or (most probably) Peter's son Peter with his step-grandmother Cordelia.

[Per his grand-daughter Zelda  Davis Howard quoting her mother, Hattie Cornia Davis]

"After the death of my father, Peter Cornia who died in Woodruff, June 29th 1887, my mother moved to Bountiful to take care of her step-mother, Cordelia Hotchkiss Carter, who lived to be almost ninety-six years old.  By living close to the temple mother was able to do a great deal of temple work which gave her much joy."
