Remick, James K. died 21 April 1840, age 23
Remick, Sally, wife of James K. Remick, died 2 March 1886, age 76

Its possible that the age for James death may have been 28, the 8 mistaken for a 3, which happens. The only way to be sure is to check the stone, if still readable.

I could not find James death from an Ancestry search.
I did find Sally's. Father is Artemus Densmore, mother is Polly K. Towns. According to her death record, Sally was born in Derry, New Hampshire in 1811, and age at death 75 years, 2 months, 4 days.

Hope this helps... Tootsie
