After marrying Isaac Jones, and after the birth of their first child, the family moved (in 1808) to land that Isaac acquired on Sugar Creek in the fourth civil district of Morgan County, Georgia. Morgan County had been formed in 1807 by the split of Baldwin County. Although Isaac Jones did not win land in this (the 1805) lottery, he purchased land from a lucky drawer. 

By September, of 1809, Thomas Clayton and his wife Milly had also moved from the Kegg Creek/Little River area of Columbia County, Georgia to Morgan County. Thomas Clayton settled on a portion of lot 219 in the fifteenth civil district, and he and Milly joined Antioch Baptist Church. The fifteenth civil district bordered the fourth civil district, which was to its west, and the homes of Thomas Clayton and Isaac Jones were actually only about two miles apart.

By 1810, two other families from the Kegg Creek/Little River area had settled on lot 219. These were the families of Nathan Jones (who had lived adjacent to Isaac Jones in 1805) and James Shaddix, whose brother had married Nancy Clayton (probably Thomas and Milly's daughter) in 1804 in Columbia County. The closeness between the families of James Shaddix and Milly Jones has led to speculation that Milly was actually a Shaddix, and this cannot be ruled out. In 1811, Thomas Clayton and his wife Milly were dismissed from Antioch Baptist Church, and it is likely that they moved from Morgan County around this time, a few miles south to Putnam County where Thomas paid taxes in 1815.

In December, 1816 Isaac Jones purchased, from Robert Shaw, lot 220 (adjacent to Nathan Jones and James Shaddix) in the fifteenth civil district of Morgan County, Georgia. He had been living, however, in the fifteenth district for a number of years, for he is listed on the rolls of Captain William Patrick's militia in 1814. The fifteenth district was Patrick's district. Also, the 1812 tax list indicates that Isaac Jones was living adjacent (or nearby) to James Shaddix and William Shaddix. It is therefore likely that Isaac had taken up the land that Thomas Clayton had vacated on lot 219. Also living nearby in 1812 were Isaac's brother Aaron Jones as well as Nathan Jones. In March of 1819, Isaac and Milly joined Antioch Baptist Church. Isaac Jones died while living here on May 8, 1821 leaving a will which names James Saddix and Milly as co-executors. 

The Creek Indians had been living on the land that now comprises Monroe County, Georgia, from long before the colonial expansion in 1540 until 1821 and the Treaty of Indian Springs. On January 8, 1821, the Treaty of Indian Springs was signed by the head chiefs, including General McIntosh, of the Creek Nation, ceding the land between the Ocmulgee and the Flint Rivers to the U.S. Government. Five counties were created from the ceded lands, Dooly, Fayette, Henry, Houston, and Monroe. The original Monroe County included all of what would become Pike County and Upson County and parts of Bibb, Butts, and Spalding Counties.

That Milly's name was Malinda (Melinda)  is known from the records of the fourth (1821) Land Lottery  of Georgia where she was registered in Patricks District, Morgan County, Georgia as "Malinda Jones, widow." Milly won lot 223 in Section 16 of Henry County, Georgia. Her children, listed as "Isaac Jones orphans" won lot 58 of Section 7 of Monroe County, Georgia. Milly is also shown on the 1822 tax list for Morgan County, Georgia as "Malindy" Jones.

On March 8, 1823, Milly Jones was dismissed from the rolls of Antioch Baptist Church, and it is likely that, at this time, she moved to Monroe County, Georgia. She remained close to the family of James Shaddix until after 1850 when he removed to Coweta County, Georgia.

John Shaddix and Nancy Clayton (daughter of Thomas) named their eldest daughter Malinda and their eldest son, Isaac. This surely could not have been a coincidence. The relationship between these families was obviously very close. Also, John Shaddix's brother James was named as co-executor of Isaac's will. This also shows a strong relationship. These facts lend support to the argument that Milly was sister of either John and James Shaddix, or more likely, of their wives Nancy and Elizabeth (Elizabeth is not known for sure to be a Clayton).

Wiley A. Clayton, the eldest son of Robert Clayton named a daughter Milly (b. 1850/51).
