He was actually enlisted AFTER Wesley A. Buchanan b: 6 Jan 1862 and his other son Thomas J. Buchanan b: 1860 d: 1861. He was enlisted 1 month later on Feb. 1, 1862 in Co. "D", 15th IA Inf. along with his older son George Washington Buchanan b: Apr. 22, 1837. They enlisted together with Samuel's other son-in-law Stephen Harry Wilkins who married Samuel's 2nd child, daughter Margaret Buchanan. ODDLY he was STILL married to Sarah Jane Toller Buchanan at the time who was 52 yrs old and would die after in 1865. VERY ODD. His 2nd wife & her mother had lived with Sarah & Samuel since 1850 in Indiana. Lucinda Ann was most likely along with her mother a Pottawattamie Tribe member. Maybe Rebecca Shaw (her mother) had lost her husband & as Samuel was trading with Indians he was given charge to care for them. So you as well incorrectly show him MARRIED to Lucinda Ann Shaw in 1862. He couldn't legally be married to both wives at same time. He was Methodist as well. What a life! 13 kids! my 2nd Gr. Grandpa!

(( )) are notes by me. ( ) are notes from original typed history.

On October 1, 1857, Mr. (Stephen H.) Wilkins married Miss Margaret Buchanan, who was born in Indiana and is the daughter of Samuel and Sarah J. (Toller) Buchanan, the former born in Pennsylvannia and the later in Indiana. Of their family of 6 children 2 are now living. ((only Margaret was ever shown)). Mr. Buchanan removed from Indiana ((missing: married 1832 Terrehaute, Ind)) to Jasper County, Illinois, & in 1855 came to Wapello County, where he & his wife both passed away.

My family notes (from History of Wapello Co page 447 under son Wesley A. Buchanan):
Samuel ((b: York Co.,)) S. Carolina. ((M: 1832 Terrehaute, Ind. to Sarah Jane TOLLER.)) At young age he was brought to Indiana where he was reared and schooled. Before reaching his majority ((manhood)) he commenced trading with the ((Pottawattomie)) Indians in Indiana, and bartered with the Pottawattomie's for some time, which he found a very lucrative business. He was married there and settled on a farm which he cultivated until he came later to Wapello County, Iowa, in 1855. ((with Sarah his wife & young children)) He located in Cass Township, where he rented a farm & coal bank, which he operated about 6 yrs (1861).

((Civil War: Just after his son Wesley A. was born Jan. 6, 1862, Samuel enlisted in 15th IA reg't, Co. D, on Feb 1, 1862 along with his son George W.ashington Buchanan, & his future son-in-law Stephen Harry Wilkins (married his dau. Margaret "Maggy"). He was wounded @ battle of Shiloh & discharged June 17, 1862. He returned back home to IA. ))

He rented land until 1871, when he moved to Keokuk township, IA & purchased 160 acres of land(s) - 80 acres of the Mathews heirs and the remaining 80 of the Litchfields. This property he farmed until his death on Jan. 18, 1898, at the age of eighty-eight years. He was very successful in business, and during his many years' residence here made many warm friends. Her married Sarah Tol(l)er, by whom he had 5 children, as follows: Nancy J. ; George W. (Washington) ; Margaret (Maggie or Maggy); Sarah A.; and Amanda ((Maddy)).

After the death of his first wife he married Lucinda Ann Shaw, by whom he also had 5 children: Wesley A. (remained unmarried) ; Ella WINTERS; Martha; Cordie (Cordia) May ((married Mr. Wm. Henry SHANK)); & Amiee ((Amy Cloretta, married Mr. (Nimrod?) POSTON- census taker)). In religious belief he was a Methodist. In Politics he was a Republican ((which by modern terms follows the current principles of the Democratic party -stood against corporations & for the common man & against slavery)), & was honored with several township offices.
Wesley A. Buchanan attended the common schools of Keokuk township, & has always lived on the old home farm. Since his father's demise he has had entire charge of the farm, & is doing well. He is a very progressive man & a prosperous future is predicted by those who are familiar with his qualifications, & his honest & upright methods of doing business. He is unmarried, & his devoted mother keeps house for him. In politics he is a firm supporter of the principles advocated by the Republican party. Fraternally he is a member of the Modern Woodsmen of America.

((My notes: He was originally buried at Mars Hill Church, Wapello Co., IA next to Sarah J. Toller Buchanan his 1st wife, but relocated next to his 2nd wife on Nov. 6, 1917 after her passing.))
