Thought this might be of interest to you. Source: "The Heritage of Johnston County North Carolina 1985," published by The Heritage of Johnston Co Book Committee, pg 248, Elijah Lassiter:
The first Lassister who can be connected with the Lassiter families of the Black Creek area of Johnston Co is Elijah who was b. in Northampton Co in 1762. James Lassiter Sr., Elijah's father, is thought to have come from the eastern shores of VA. In his will in 1804, James Lassiter Sr. named as heirs his wife Lydia, 7 sons: Shadrack, Elias, Greene, Elijah, James, Kinchen and Jordan, and 4 daus.: Penelope, Henretty, Abigail and Reiniford. It was Elijah who came to Johnston Co after the Revolution, settled on Black Creek, now Elevation Twp, and started the Lassiter family which still inhabits much of that part of Johnston Co.
On Feb 25, 1834, at the age of 71 yrs, Elijah appeared in the Court of Pleas and Quarter Sessions of Johnston Co and swore to a deposition describing what he did for the new country in the Great Revolution, thereby leaving a first-hand account of his early life. A summary of his deposition contains the following: "... at present a resident of Johnston Co and has been for nearly 50 yrs having removed from Northampton Co where he was born ... in his 16th or 17th yr, he was drafted in the Militia of this State ... marched to Smithfield, Johnston Co ... across the Cape Fear River ... crossed the Yadkin at Shallow Ford, then down the Pee Dee River in SC ... where an engagement took place between the American and British forces ... here the American army was defeated. Became ill, returned home, and after 2 yrs was drafted again. Marched from Halifax to Smithfield then to Cross Creek - now Fayetteville - then by Duplin Courthouse to the Town of Wilmington to meet the British army. At Wilmington word was received of the surrender of Cornwallis - then they marched back to Tarborough where he received discharge - term of service for his country embracing altogether a period of 6 months."
In 1800 the family of Elijah was the only Lassiter family in Johnston Co. By 1827 he owned more than 1,500a. lying chiefly between Black and Middle Creeks.
No information exists about Elijah's wife, but he had 12 children who survived to marry and establish families of their own, several of whom produced large families. There were 6 sons: (1) The oldest, William, b. in 1791, m. Luch Stephenson in 1813, was the executor of his father's will in 1848, had 10 children; (2) Jason m. Thena H. Cotton in 1825, moved out of Johnston Co before the 1840 census; (3) Shadrack, b. 1803, m. Lucy Johnson in 1825, remained and produced some of the families who still live in the Lassiter community, does not appear in 1870 census - probably died before that time; (4) Elisha m. Obedience Carrell in 1827 and they too stayed on the Lassiter land; (5) James m. Lucy Lockhart and remained in Johnston Co in the Smithfield area; (6) Elijah Jr. m. Mary Tomlinson of Johnston Co in 1826 and moved to Pike Co, AL. The daus: Sally, who m. Solomon Whittenton and moved with her husband and brothers Elijah Jr. to Pike Co, AL. Elijah Jr and Sally appointed a Johnston Co attorney to collect their part of Elijah Sr.'s estate at his death in 1848. Elijah Sr.'s dau. Lucy m. James Johnson, Penelope m. George Stephenson, Tabitha m. George Johnson, Patsy m. John Carrol, and Mary m. Gideon Woodall.
Thus were established the 12 families from Elijah Lassiter, the first of his name to settle in Johnston Co.
