Dang. I knew there was something I was supposed to be looking up for
you - that was it.
I've not used the 'grafting' Parafilm, as I've got ready access to
the 'good old' Parafilm M, and saw no need to switch.
A 2" x 250' roll does a LOT of grafts.
I typically cut it into roughly 6" x 2/3" strips for routine
use. Most grafts use up one or two strips.

If it's scionwood I sent you, it's Thomas Myers(aka Hay), which is
probably the best BW for this part of the country(Ohio River & south)
- large nut(20/lb), thin shell, kernel % in the 38% range,
lateral-bearing, anthracnose-resistant, and annual-bearing.
Emma Kay has an 'odd', elongate football shape, as well - very unlike
most of the 'round' BWs I was familiar with, and it is typically
heavy-bearing, lateral-bearing, with thin shell and high kernel quality.
I mean, if the previous groundskeeper had planted hicans,

Sounds like a reasonable likelihood, to me.
Even if they're seedlings of named varieties, it sounds like they're
an easy-cracking selection, and might be worthy of evaluation and propagation.
