Just been listening to the David Lindley tune on Spotify. His is a fiddle-led instrumental, with no lyrics. A lovely tune! I asked MOH, "What does this sound like?" (knowing that she's very familiar with "Dear Someone"). Her immediate response was, "Are You Lonesome Tonight". That's another good point to consider.

"Dear Someone" may well have been based on "I Always Knew....", but it's been turned into a truly beautiful song. Gillian Welch has borrowed and adapted many other old tunes and lyrics and has created a lovely library in the process. She is part of the tradition, still within it, and developing it.
