What I have (no proof) is:
Phobe 'Catharine' Lugar
born abt 1846 in Giles (d/o John Lugar & Margaret Duncan)
married 27 Nov 1888 in Craig County, VA to
Andrew Jackson Caldwell (s/o James & Catherine Caldwell)
They had Nannie Apr 1884 in Craig County, VA
But this line has given me a bad time and I am not sure I would trust. Hope someone else replies with a better answer.
