William Kemp Culbreth was the oldest son of Thomas Culbreth and Ann Eliza Peabody. For a time he lived with his Aunt Mary Culbreth, Thomas' sister, where he helped tend her farm. He married Margaret Morris Pearsall of Wilmington, North Carolina, on October 19, 1881. Margaret, or Maggie, was a school teacher. Maggie's mother, Lucy Pearsall lived with the family for some time. She was a small woman, rendered deaf mute as an infant. She was known as "Little Grandma" and signed through a black woman who lived with the family. 

William Kemp, or W.K., was an vocal proponent of agriculture and ran for Sheriff of Robeson County several times on the Republican ticket. He was active in the Populist movement and the Grange. He was appointed road supervisor and served as Post Master in the Purvis Community. To his detractors he was known as "Windy Billy" for his long winded speeches and harangues of the local political establishment. 

He operated a mill at Moss Neck Depot with his brother Malcolm Nathaniel Culbreth. 

Following the death of Maggie Pearsall in 1924, he married Nealie Smith, on July 4, 1927. He was seventy-one and she was twenty seven. According to family lore,  when W.K. Culbreth died in 1928, his daughters packed Nealie's belongings, put her on a mule and sent her down the road. 

John Thomas Culbreath was the second son of Thomas Culbreath and Ann Eliza Peabody. He moved to Effingham County, Georgia, where he met his wife Mary Peavy in 1881. He was drawn to the area by the booming turpentine industry. He later moved to Wakulla County, Florida and is buried in Tallahassee. 

Of note is his retention of the "a" in Culbreath. The cause of this spelling is unknown but it is most likely that it is simply the result of the standardization of spelling in the area.

Joseph Warren Culbreth was the third son of Thomas Culbreth and Ann Eliza Peabody. He was a successful farmer and timber merchant. He married his second cousin, Elizabeth Young McNeill on February 22, 1888. Joseph served as Postmaster at the Moss Neck Depot until his early death in 1900. 

Malcolm Nathaniel "Make" Culbreth was the fourth son of Thomas Culbreth and Ann Eliza Peabody. He lived in the Moss Neck community, where he operated a cotton gin. Make also served as Post Master at the Moss Neck depot. Malcolm married Katie Duncan on September 28, 1892.  

He was a leader in the Grange and local Republican Party.
