maybe died 1862
age at death 21 years, 10 months, 28 days.
if she died in 1862, then age would have been ~16, making marriage
to Denniston questionable. Need to check 1865 census.
may have married Martin Jay Denniston, who was living with them
in 1860. He served in the Civil War, and later married someone named
Jennie, who's parents were from Canada.
