Benjamin would have been about seventeen years of age when he left Virginia for Ohio with his father and family. The Roebucks went to Ross County, OH and there on July 6, 1807, Benjamin and Elizabeth Russell married. Elizabeth was a daughter of John Russell, a Virginian who migrated first to Ross County and later to Lawrence County, OH, where he died and left a will. John Russell wrote his will May 18, 1820 and it was probated April 11, 1825. He mentioned his daughters, Rachel Roebuck and Elizabeth Roebuck. He left land to his sons Jeremiah and Sanders in Ross County on the banks of Walnut Creek. Other sons and daughters included Jemima, Ann, Ginzeey, Arminia, Thomas, Manoah, and Francis who was under age. Three other sons named James, John and Lawrence were mentioned.

Benjamin Roebuck served in Lt. John Devault's Company, Stewart's Regiment, 3rd Ohio Militia from July 26 to August 16, 1813. He was a private, "remained in service and was fit for duty" during the War of 1812.

Benjamin Roebuck, Sr. was the first permanent settler of Center Township [Mercer County, OH]. He settled on the St. Marys and Ft. Wayne road at the crossing of Twelve Mile creek in Section 5 in 1825, kept a tavern or public house for travelers for many years. Early Methodist preachers on their circuits made his house a place for meetings until his death in 1843. His sons, Lorenzo, Greenley, and William, and all his daughters became residents of Center and Union Townships, but all are dead now except the oldest daughter Frances, wife of William Cain of Center Township. (1876).

The 1820 Census of Mercer County, Ohio is given here in its entirety. Out of a total of 96 persons, not counting those who were not yet naturalized, Roebucks and relatives account for 35. Compared to the Mercer County population of 96 people, Darke County, Ohio, just to the south, in 1820, in the same categories, had a population of 3,681.

From the Western Christian Advocate:
Departed this life, in great peace, at his residence in Mercer county, O., December 17, 1842, Benjamin ROEBUCK. He was born in the state of Virginia, from whence he removed to Ross county, O., where he embraced religion and joined the Methodist Episcopal Church, and lived a consistent and exemplary member for about thirty-six years. Brother Roebuck was one of the first settlers of this new country. He came here and pitched his tent, and erected his altar of worship, while the war whoop of the Indian was yet heard. He was here eight years before he heard a Methodist sermon preached; but still he maintained his integrity in the cause of God; and when the missionaries of the cross came, they found an asylum under his roof--his house was the preacher's home. Death was no terror to him; his work was done. During his illness, he spoke of his latter end in great calmness and resignation. "Precious in the sight of the Lord is the death of his saints." In his death the Church has sustained a great loss, the family a kind husband and an affectionate father.

In 1819, John Roebuck, Ruel Roebuck, Benjamin Roebuck, Michael Harner, Samuel Hanson, and William Baker from old Fayette County, Ohio, and John Van Gundy from Ross County, moved to Shanes Prairie. Van Gundy, Harner, and Hanson afterwards became residents of Union Township [Mercer County, Ohio] and Benjamin Roebuck of Center Township, Mercer County, Ohio.
