Hiram Dixon was born on April 5, 1818 in Kentucky. Hiram Dixon married Elizabeth Cappell in 1837. She was the daughter of Warren and Emma Cappell. The Cappells were the founders of the city of Cappell. The Cappells were very wealthy and they did not approve of Hiram's and Elizabeth's pending marriage.  The Cappells disowned Elizabeth after she married Hiram.

Hiram and Elizabeth had four boys. John Samuel Dixon married Lillian Payne. Ed Dixon married Annie Zacha.  Tom Hiram Dixon married Lynn Lawrence. Lotus Dixon married Mary Motley. This branch of the Dixon family tree made their home on the family farm located 30 miles from Tom Dixon's house.

In 1839, the Jonas Family moved to Dorinda and purchased 63% of the land from the Dixon Family. After a few years, the Jonas family was receiving more credit for founding Dorinda than Tom W. Dixon was.  This angered Hiram Dixon. Hiram began to fight to save his family's legacy. He and his sister, Dorinda Dixon, lobbied to have several sites in Dorinda marked as national landmarks to honor Tom W. Dixon and the Dixon family.  Several members of the Jonas family objected to this.  These members of the Jonas family felt that the Dixon Family name required no recognition since the Jonases owned the majority of the land in Dorinda. Hiram and Dorinda continued to lobby for the deserved recognition.

After a year, Dorinda lost hope of her family ever receiving recognition from the Jonas.  She gave up the struggle because it was disrupting her family life.  Hiram was determined and stubborn and he continued to fight.

In 1841, Hiram Dixon, Ester Dixon's husband, Marion Bethurum, and Dorinda Dixon's husband, William Dougan, joined forces with Paul Brown, Bill Lane, and Don Flack. They opened several businesses in Dorinda. The businesses were a steel mill, a clothing shop, a general store, a stable, a stage coach company, and a bank.

Hiram gained one ally in his fight to obtain recognition for his families' name in 1942, Cyrus Jonas, a son of Charles Jonas.  Cyrus helped Hiram lobby to get recognition for the Dixon family.  The two men remained friends until 1859.

In 1859, Hiram was involved in a deal with Cyrus Jonas that sparked the Jonas-Dixon Feud.  Hiram served time in jail before he was acquitted for the murder of Cyrus Jonas. In 1862, he was instrumental in calling a truce between the two feuding families.

Hiram died from suffocation in 1894. Hiram's family believed that a member of the Jonas family murdered Hiram, although it could never be proven.  Hiram died without seeing his family receive their well-deserved recognition. Hiram is buried in the Dixon Family Cemetery.
