Died: At his residence in Sumner, Iowa, on July 6, 1881, John Bingham, aged 69 years, 4 months, and 10days.
John Bingham was a native of Vermont. In 1834 he married, and emigrated to Illinois, where he remained till 1856, when he came to Iowa and settled in Leroy township, Bremer county, on the present Bingham farm. In 1875 he left his farm and removed to Sumner, where he has since resided. He was for many years a member of the U. B. Church, but in '72 he joined the M. E. Church with which he remained until his death. He was a useful and highly esteemed citizen, and a man honored for his uprightness and integrity. The funeral services took place at the residence, Rev. Keeler, D.D., officiating, and the remains were laid at rest in the Wilson Grove
Cemetery.

Daughter of William and Olive Horton. First husband James V. Ditmar[s] died August 10, 1863 while stationed with the Company D of the 38th Iowa Infantry in the swamps near Vicksburg, MS.They lived in Ionia County MI in the 1850s where James worked as a lumberman. At some point between the 1854 MI census when James Ditmars is still in Otisco Twp, Ionia Co, MI and 1860, they moved to Iowa.

In 1900, she has living with her "niece" Ella Bingham, b. Mar 1881 in Iowa, whose parents were born in Iowa and NY. Since none of John's brothers or sons were born in Iowa, obviously something's incorrect.

James and Charlotte Ditmars' only child was a son, Henry J. Ditmars, who married Mary Amelia Near. Mary Amelia Near had two sisters, Phebe and Hattie, who married William Eugene and Theron Bingham, both sons of James Bingham, who was John's younger brother. Ella therefore may have been her daughter-in-law's niece.
