Samuel and Olive "Jane" were members of the seventh Day Baptist Church.
The 1860 Census showed Samuel A. Champlin (30), farmer, living at Genesee, Allegany County, N Y, with his wife Olive A. (26) and children Leroy D. (9) and Myrta V. (3).
According to the 1900 Census Samuel was living at the home of his son, LeRoy Champlin, at Ceres, McKean County, Pennsylvania, and it showed his birth year as 1829. His wife Olive "Jane " was shown living with their daughter Eva at 146 North Main Street, Alfred, NY. The 1910 Census again showed Samuel (80) living with Leroy at Ceres, McKean County, PA.
From a (slightly edited) hand written account of "FATHER'S ARMY SERVICE": Samuel enlisted in the army in March, 1864, at Alfred and served in the Elmira Regiment: the 179th New York V olunteer Infantry, Company "B", under Captain Stewart of Horseheads, NY. The army stayed at Elmira until May 27th when they went to Arlington Heights. Samuel was a cook. After 2 o r 3 weeks of drilling, they went down the Potomac River to the Chesepeake, which they crossed , then up the James River as far as White House Landing. A few days later, June 17th, they engaged the enemy near Cold Harbour. By next morning, only 7 members of Company "B" still survivied. Samuel was shot in the wrist and later, while lying low, took a bullet in the spine. This, and the concussion of firearms nearby, "touched his brain so that he was ever afterwards insane". In the following months Samuel spent time in City Point Hospital and then was given a furlough home, but was unable to get there for a few weeks due to low water levels in the river. He spent this time in Alexandria where he suffered from bloody dysentery. After finally arriving home, Samuel was ordered to report to the hospital in Elmira where he remained for three months - at which time he was then ordered to return to the front. When he arrived in Washington, Samuel was judged to be unfit to serve and put back in hospital. He was finally discharged in June 1865 and went home to live until March 1868. He was finally thought to be too dangerous to himself and was admitted to St. Elizabeth Hospital in Washington, DC, where he remained for many years in "Quiet insanity from which he never rallied".
The Surrogate's Court at Belmont, NY has on file a Letter of Administration showing Samuel died at King's Run, PA on 2 May 1913 and he was survived by his wife Jane C. of Alfred; son Leroy of King's Run; daughter Eva St. Clair of Alfred; daughter Myrtle Benjamin of Richburg, N Y and daughter Ellen Vincent of Alfred.

Olive and Samuel's grandson (son of LeRoy) Ross Champlin wrote that he recalled his grandmother walking all the way from her farm on the hill to watch the first train come through Alfred Station from Hornell. She sat on the bank by the track and waited for the train with many others. They tied their horses to a rail fence, but when the train came, the horses panicked and bolted breaking the entire fence.
