Your remark that your ancestor, Elihu Adams, was a sibling of President John ADAMS and had a NC connection was interesting to me because of the following article about my maternal ancestors, Stephen Marion HAIRGROVE and Nancy Mary BROWN, of Guildord Co., NC; Bedford Co., TN; and Shelby Co., TX. Note that the article mentioned that 'Captain HAIRGROVE was descended from the ADAMS family and was related to President ADAMS.'
Preliminary research of the families of the children of President John ADAMS gave no particular clue about where to begin research about a possible HAIRGROVE/ADAMS relationship; therefore, I thought that the siblings of President John ADAMS might be a better place to begin research to trace the possible relationship.

'Stephen Marion Hairgrove and Nancy Mary Brown were married August 29, 1805 in her native state of North Carolina. Her husband was born in North Carolina also, July 24, 1784. He was only twenty-one and she eighteen years of age when married.
Both belonged to good families. Captain Hairgrove was descended from the Adams family and was related to President Adams. Mrs. Hairgrove was a niece of George Pope, a leading Baptist minister of North Carolina.
The year after their marriage, in 1806, they emigrated to the Duck River Purchase in middle Tennessee, becoming a part of the most noble heroes and heroines known in our history, who under the Jacksons, Boones, Harrisons, and other brave leaders, drove back the savages and peopled the great Mississippi Valley, extending our country from a mere strip on the Atlantic to the regions beyond the "Father of Waters" and building up great communities which are destined to control our great country. They both inherited those hardy and noble qualities from the ancestors of the Revolution and those heroic ages preceding which peculiarly fitted them for the duties attending the settlement of this savage frontier.
Captain Hairgrove was a soldier under General Jackson in the British and Indian Wars of 1812. On an important occasion [at the time of the desertion], he held Fort Jackson in the Heart of the Creek Nation with only seventy men, and his brave and patriotic services on that occasion were highly complimented by his Commander-in-chief, General Jackson. The subjects of this sketch spent nearly half a century in Tennessee, from its early settlement until it became one of the leading states in the South and West.
They had twelve children, eleven of whom they were happy in raising to years of manhood and womanhood. Their children, like their exemplary parents, in their early years desired to move West, and in common with thousands of Tennesseeans, determined to make their future home in the great state of the Southwest, our noble Texas. So in 1853, they removed from Bedford County, Tennessee and settled in Shelby County, Texas.
Mr. Hairgrove always took a great interest in politics and was always ready to serve his country, either in the field or at home. He was a well informed politician and the friend and associate of General Jackson, General Houston, President Polk, and all the leading and prominent men of his state and party of his day. He voted in every presidential election from the time of Thomas Jefferson, the great Republican leader and defender, down to President Buchanan.
Mr. Hairgrove died at his residence near Buene Vista, Shelby County, Texas on December 11, 1858 in his 75th year, his devoted consort surviving him nearly 22 years.'
