Not finding any census of the Hall family
I did though find a Franklin Co,. VA marriage record
for Elisha Hall and Pollie Leffue Aug 20 1834

With the name Hall it is too common to find records.
I did though find in the 1830 Franklin Co. VA a most possible census for the Leffue household.
There is one Elysa Leffew with a daughter listed in the 15-19 yr range, which could be Pollie. There is also one more daughter in the 10-14 yr age which I would say is more likely Pollie with her possibly being 18 yrs of age in 1834 marriage.

I found four Lieffew/Leffew families in 1830 in Franklin Co VA
Enoch
Westly
Elya
Elijiah
