This must not be the same Dougal.My Dougal was born 1765 in Scotland and died 1840 in Covington, MS.He married Dicey (?) in NC and their children were James Duncan, Allen, Jacob, John and Alexander, Jane and Harriett.I believe some of these might be nieces and nephews.Most were born in Simpson Co, NC and they moved to Covington, MS about 1810-1820.
Listed in an old Family Bible is: Santa McPhail - Jacob's dad (Santa=Alexander?) E-Dow son Santa Allen Jasper William Jacob Aunt Jane 7 brothers came from Ireland with their father.Their mother stayed behind.All from Ireland - Scotch-Irish.
Do you have anything in your book that refers to any of these people?
