There are dozens of us!

I run a nonprofit group that maintains a similar but different database, ours focuses on identification of heritage varieties, I.e. apples that existed pre WWII. We're in the PNW so we also have catalogs of where they were sold to make their way to us, etc, as we identify trees in old orchards.

I've learned some interesting stuff along the way, like that English varieties keep showing up in eastern Washington because English nurseries shipped to Vancouver in the late 1800s.
