I have only been able to trace my line back to a Duncan McQuagge/McQuaig born ca 1765 who came from North/South Carolina to the Euchee Valley Scotch settlement in Walton County, Florida in the 1820's. Census records show him first in the 1820 Census of Conecuh County, Alabama as Duncan McQuaig; then in the 1821 Census of West Florida as Duncan McQuagge; and finally in the 1830 Walton County Florida Census as Duncan McQuagg. He obtained a land grant on May 15, 1829 in Walton County for 80 acres in Section 12,T2N,R18W as Duncan McQuaig. His son Norman McQuagge is my great great grandfather.
There are other previous census records such as the 1790 Census of Richmond County, NC as Duncan McQuig; December 1795 Petition for Military Organization as Dunkin McQuag (Line 5), and the 1810 Anson County NC Census as Duncan McQuague. It is unclear whether any of these are the same Duncan.
Some in my family believe that Duncan's father was named Malcolm. There is a Malcolm McCuaig from Cumberland County listed in "Roll of Soldiers belonging to the North Carolina Highland Regiment who served in the North Carolina Militia before their Enlistment" (http://www.members.aol.com/HoseyGen/NCLOYAL2.HTML#XI). A Malcolm McCuag's estate was probated in Cumberland County in 1786.
A Malcom and Peter McCuagge are listed in the 1786 North Carolina Census of Richmond County; and Malcom and Peter McQuig are listed in the 1790 Federal Census of Richmond County along with Duncan McQuig. Peter and Duncan must be the brothers or sons of Malcom.
I would like to correspond with anyone who has additional information on these individuals.
