This is what I've come up with. William Albertson b abt 1775 m'd 16 Nov 1797 Elizabeth Powley b abt 1775.
Five kids Rebekah 1796
Nancy Ann( Lucinda) 1796
William Jr. 1806
John Gates m's Elizabeth Powley abt 1806 one son John Gates born 22 Mar 1804 m'd Caroline Elizabeth Bryan
Humphrey Smith m'd Elizabeth Powley 16 June 1813 one son Charles Powley Smith born 15 Feb 1811.
That's what's in the IGI files folks with other families supporting the info.
There are other similar names in the following generations. That could be where the confusion reigns.
