She may have died in Greenville, Montcalm, Michigan. She was there with her son-in-law and daugher, John and Lucy Conklin? during the 1870 Michigan Census, but not with them in the 1880 Michigan Census in the same place. She may have died between 1870 and 1880. Angelica's husband was Durlin Crego.
I am also looking for Angelica's daughter, Anna Crego-Whitbeck's death and burial information. She must have died after the 1880 Michigan Census, when she was living with her husband, Johnathan Whitbeck, in Beaver, Bay Co., Michigan. Also, where is Johnathan Whitbeck buried? He died in 12/15/1893 in Deerfield, Livingston, Michigan?
