Because Scottish and Irish people hated the British Royals, they willing signed up to fight the British in the Rev. War and the War of 1812.  As a reward, they were given landgrants to Miss., Alabama, and Ga. in the 1800s.  Many of the families were down line from Robert of Bruce, John of Gaunt, Queen Margaret York Tudor and King James Stewart.  Land was wealth and they worked hard as land owners, and they had large families.  I will have more of the lines as I get them prepared for publishing.
