The reason I believe Robert M Scott is their son is the info below need some help looking at this please, Thanks..
Sarah Fugusons dad wasn't happen with the marriage to Thomas Scott maybe a religious belief dispute,?
now if you look at the 1830 census I have on Thomas Scott's profile you will see a son age 5 to 9 I believe this is Robert M Scott b.bet.1818 \1825 I got these dates on Robert M Scott census he was in Pickens,sc married to Lucinda Breazeale ,Robert at this time is listed on Thomas Scott's brother's profile Patrick Scott b.1786 I may need to move him?
Robert Scott also has a Mahalia Martin living with him on the 1860 census Pickens,sc at age 55 but this Thomas Scott b.1794 has a daughter Mahalia Scott born 1820 listed on Thomas Scott 1850 census in Alabama, Thanks for any information
