I don't like it, but of the combos, Shepherd Vaughn and Shepherd Matthias are best.
Years ago I did some research on the earliest names recorded for births in the first European colony on the east coast of Australia, and there was a woman named Shepherdess who named her daughter Shepherdess. I thought that was rather fascinating.
