John(1804) >William(1767)>Daniel McQueen(1725)>Isle of Skye,Scotland

Hit a wall on my ancestry:I have John McQueen (1804--) married Emily Goodson(b.1810, S.C.)in Montgomery, Alabama on December 10, 1822.I need his death date, place; her death date, place.John's father was William McQueen, born ?, 1767 in ? S.C.;married Judith Hardwick (no date or place).She was born in 1778; no other dates. William's father was Daniel McQueen, who was born 1725, Isle of Skye, Scotland; immigrated about 1748 to Horry District, S.C., married Ruth Jenkins (1730-)in 1750 in S.C. (Horry Dist.)He died 1785/1797 in S.C.That is where my trail ends.Can anyone fill the blanks, or take me further back.Thanks.Tina owen
