I will write a G2G about her. At the time you PPP's I was still working on four profiles at once and hadn't finished Hannah's.
Hannah was actually (probably) the biological daughter of John Browne-27 and was possibly or probably the step-daughter of William Potter. It seems she took her step-father's name, or this is the name by which we know her.
Her father on WikiTree was previously Potter-142 (I think), but because the two William Potters are often confounded her "correct" Potter father is now Potter-1209.
However, she was probably the biological child of Browne-27.
None of this is proved, but Anderson calls the circumstantial evidence "highly suggestive."
Thank you, Anne!
