From the notes in the bio:
Note: Adopting orphan and disconnecting Hester as the daughter of Samuel Allen-1783 and his wife Mary Unknown-179058. Hester is commonly included with this family, however I'm not finding any documented sources that include her with the other children of Samuel & Mary Allen.

Further research has shown nothing but unsourced family trees that could be mistake, conjecture, copied from each other.
I wonder if she was confused with this Hester Allen, a daughter of a different Samuel Allen? Years are off a bit, but possible:
