Hi, As far as I can tell your Pulliam line doesn't connect with mine but I found the marriage record for Lucy and Daniel but it was in NC and not VA. You said that Lucy was born about 1832 but that is when this record shows them as being married. I'll see what else I can find for you.
Name: Daniel Dunnavant Gender: Male
Spouse: Lucy Pulliam Spouse Gender: Female
Marriage Date: 29 Sep 1832 Marriage County: Rockingham Marriage State: North Carolina
