chiefbeaz,
Lucky Clover Farm acquired Maria's varieties (and much of Gary Millwood's collection) three years ago. I haven't kept up after that so you might want to contact them directly to ask if they are keeping the seed stock fresh and if it is available. Almost all of the KY heirlooms I sourced from Maria did exceptional here in So Cal and were standout varieties.
If you find out anything please post back... their facebook page is here:
