I know of John McComas who married Catherine Hatfield as yet another Hatfield-McComas connection. I don't have alot on the Hatfields and those names don't look familiar. As for "Minnie" being known as Lennie, it's highly possible and not out of the question. Especially as knowing her father is buried there as well. Her original name could also have been Melanie so look at the end, 'Lanie' or as you have it shown 'Livnie' both are not far removed from the name Lennie.
