I was having some fun trying to figure out the
location and searched the census for the names listed.
 I found many of the children listed on the 1910
census of Woods County, Alva, Wards 2-4.  After
searching all last night and all today, I decided I
was certain enough to write you.  I don't know what
school it is or the exact year.  I don't know if it's
good enough (legal) to post this data I've collected
alone, but I will give you the info. I found and you
can go from there.  Once you've visited the site, they
allow you to download it to your computer from there,
you will see the names listed. 

The following is a list of the names I found, the
spellings as presented on the site where I found them
and their location:

Elizabeth Lander (as Landers on census) ward 4, age 12
Viola Muckey wd 4, age 14
Blanch Miller, wd 4, age 13
