Going at this sideways via census data shows AR Hannah's sister Philena had 2 childr. b. MO c 1870s before she landed in Illinois c1880. Coincidental to MO Hannah's known residence in MO in the 1870s.
MO Hannah married David Dill - he was in AR 1860 (BLM Land Records David Dill); also among their childr. are those named George, Ellen, Nancy Ann and Emma Philena - names of AR Hannah's parents and sisters passed down...
Seems reasonable to say AR Hannah (b. Gallia OH) is same pers. as MO Hannah.
The other two are separate Hannahs - so 3 profiles should be made for 3 Hannahs.
