Kirby I am untangling this family slowly. As appropo I will post interesting info to help flesh out the family story.

Capt Thomas Waller Todd's father, Neriah Todd appears in the 1830 MO census in Howard County married with one slave. His Nativity is Kentucky. By 1850 slave census he had 9 slaves and by 1860 was up to 11. Neriah had a bunch of kids including Neriah Paul Todd who served in Capt. TW Todd's company of Perkins organization. See the below death notice and then the notes from the Howard County History about both Neriah's father and son. Capt. TW Todd had a younger brother Chenault born 1850 and appears to not have been old enough to participate with his two older siblings in the unit.

Sudden Death of N. P. Todd
"In the midst of life we are in death!" How appropriate are these words in this case. On Saturday morming our citizens were shocked to hear that Mr. N. P. Todd had dropped dead of heart disease; they could barely believe the report for he was in Fayette the day before in the best of health, and was seen at his farm by persons coming to town Saturday morning. But the report was only too true. Saturday morning in company with his little son Jimiew he left the house horseback to stop some holes in the fence along the lane that leads to George Hammond's. He left his son on the horse and got off to do some work and while thus engaged was stricken. He was evidently on top of the embankment when stricken, and after falling his body rolled to the bottom of the little ravine. His little son soon realized that something had befallen his father and after seeing the silent form, hastened home to give the alarm. Members of the family and Mr. Hamp Woods, his brother-in-law, were soon beside the body, but he was cold in death. The grief of the family can only be imagined, and their loss is irrepairable. Mr. Todd was a son of the late Neriah Todd, and was born August 26, 1843, in this county where he had always had his home. In 1864, when 21 years of age, he enlisted in Company E, commanded by T. W. Todd, in Perkins battalion, and served until the general surrender in 1865. He was a brave and loyal soldier. He was an honored member of John B. Clark Camp of Confederate Veterans. He was married February 10, 1874 to Miss Mary J. Afflick, who, with nine children survive him. Mr. Todd was one of the foremost citizens of Howard County, a successful farmer and active Democratic politician. Funeral services were conducted at the residence Monday by Elder Wm. Huff of Mexico, after which his remains were interred in the city cemetery. The funeral procession was one of the largest ever seen in the county, attesting to the high esteem in which the deceased was held. To the bereaved ones we extend out deepest sympathies.

NERIAH TODD, farmer and breeder of blooded stock. Even before the war, central Missouri had a widespread reputation throughout the Mississippi and Missouri river states as an important centre of blooded stock. Conspicuous among the citizens of Howard county who have engaged largely in this business is Neriah TODD, the subject of this sketch, and his son Chenault. It is not, of course, the province of a biographical outline to give in detail the business in which its subject is engaged, and the fact can therefore only be noted that the Messrs. TODD, father and son, rank among the prominent short-horn stockmen of the county. Mr. N. TODD has a farm of 526 acres and makes a specialty of raising Durham cattle, of which he has one of the finest herds in the county. His son is largely engaged in this business, having begun in 1870, buying his breeders from the best stock in Kentucky and Illinois. He has a large herd, at the head of which is "Sharon Geneva," a fine Durham bullock, of the pure Rose of Sharon breed, raised by Mr. A. Renick, of Kentucky. Neriah TODD's father, Thomas TODD, was a native of North Carolina, and was born December 25, 1771. He came to Kentucky in 1790, and March 5, 1795, married Mary CHENAULT, of the latter state, who was born May 14, 1775. They had eight children, of whom Neriah TODD was one. In 1816, when young Neriah TODD was but twelve years old, they immigrated to Howard county, Missouri, settling first at New Franklin, and afterward, in 1820, they settled on the place where Neriah now lives, and where his parents died. His father died June 12, 1857, and his mother, June 2, 1834. Mr. TODD, the father, was prominently identified with the development of Howard county, and was regarded as an intelligent, energetic and upright citizen and farmer. Neriah was born in Madison county, Kentucky, December 4, 1804, but principally reared in this county. He lived with his father on the home farm until 1829, when he improved a farm in Section 2, but returned to the home in 1850. He was married December 15, 1829, to Miss Minerva, who was born in Kentucky June 2, 1806, a daughter of William HOCKER, an old citizen of Howard county, he having settled there in 1824, and of this marriage there are eight children: William, Thomas, Eugene, James, Sarah, Neriah Jr., Elizabeth, and Chenault. He has been a member of the Baptist church thirty years.
