Who are the parents of Phebe Asher b. 1815. Ky. Who is her husband, child and grand child?

I've run across many Dillion Ashers who could be Phebe's father, but I am told none of those are correct. I have found one saying that Phebe married a John Allen, then I have also found John Allen married an Emelia Nunnally. I need help straightening this mess out. Phebe's child should be my grandmother Martha Allen which married a Mathias Gabbard.
