There isn't too much available online about American persimmon cultivars; I found the NC State Extension to be useful for summaries of named commercial varieties:
https://plants.ces.ncsu.edu/plants/diospyros-virginiana/ARS Plant Germplasm database, misc. varieties when you search by species:
https://npgsweb.ars-grin.gov/gringlobal/searchOut of everything I read (briefly) about Mr. Lehman, looks like his most popular varieties in terms of current availability are the "Morris Burton" (low production, small fruit) and "Jerry Lehman's Delight 100-46" [F-100 cross] (good fruit quality and production)
The "Growing Fruit" forum has pages and pages of misc. threads on his work. Forum member "Barkslip" there seems to be currently active and has had access to Lehman's crosses budwood.
Never saw these growing up where I was in IL, wish I knew more. Personally, I would think the self-fertile commercial varieties, like Meader and Prok, would be easiest and most efficient to grow, unless you plan on doing persimmon breeding as well.
