Elizabeth Ann Blankenship (Belcher) - Maiden Name

Wahs Elizabeth a Belcher or a Ligon? Is she connected to the correct parents, who aren't Belchers?

Asking because my son has paternal Belcher cousin lines and I don't know if she connects to them or not.

There aren't any notes in her profile to shed any light on why her maiden name is different from her parents' surname, so thanks in advance for any additional info.
