Harriet is the only one of this family that we do not know where she went, who she married or when she died. The rest we have documented.
Do you know when and where your Harriet Dacus Stancil died? Was there an Obit, death certificate? Same question on Hugh Milender Stancil(your grandfather) Was your grandfather the first child born and in which county in Tennessee.
There are other Dacus families connected to Mansfield Walker Dacus in Tennessee. If we connect, I can give you more information back to 1757. Here is hoping we can connect.
