The Earl family letters contain correspondence between members and friends of the Earl family in New York, Michigan, and Missouri, written during the latter half of the 19th century. Most letters are addressed to Jane Layton before and after her marriage to Sanford Earl and have news about friends in New York and Michigan. One frequent correspondent, Ann Maria Adams, described life in rural Michigan. Several Earl family members wrote from Pembroke, New York, about family news and social activities. The collection also has three detailed letters that David E. Earl, a farmer in Avola, Missouri, wrote in 1874 and 1875. He discussed life in the rural Midwest, agricultural prices, and the effect of national politics on the local economy. An undated poem is entitled "Do they miss me at home."
