I incorporated the input and comments I received and published the paper on academia.org, here:
I added a useful table which shows that during the school year 1814-1815 on Moor’s school roster there were a lot of changes in the student body.
Hyrum Smith appears on the roster for Moor's school in the first quarter of the 1814/1815 school year, but not after that.
30 of the 57 students (53%) enrolled in the first quarter along with Hyrum did not return for the second quarter. This means Hyrum's absence was typical. Perhaps that was due to the epidemic.
Only 14 of the 57 students (25%) enrolled in the first quarter completed all four quarters in 1814-15.
Several students were added in every quarter, but the total number of students declined every quarter, from 57 to 52 to 39 to 37. This may be another indication of the impact of the epidemic.
