Although this stone is broken, her name caught my my eye:
Alzina Wing-Walnut Hill-Baraboo
Alzina Niles Wing, wife of John Wing, is buried in the Walnut Hill cemetery in Baraboo, WI.  Looking for her on Ancestry, I found her death record, which indicated that she died on June 20, 1869 from “Schirus Stomach.”   What’s that?  Apparently, some kind of stomach cancer, from what I can tell.

The 1860 census shows her as married to John Wing, age 53, and with two children, Hannah and Aaneth.

By the 1870 census, John Wing is shown alone, with his occupational status as “at home,” (in 1860, he was listed as a farmer).
