Richard (1381-1444) was the son of Richard [de] Bayley and Margaret [de] Sherburne. At some point (don't know when, but likely to have been in early childhood), he adopted (or was given) his mother's family name; he's pretty universally called Richard [de] Sherburne, and his children took the name Sherburne.
(There are reliable sources for the above, and all that.)
I think this means that his LNAB, which is currently Sherburne, should be changed to Bayley, and Sherburne should be his CLN.
It's slightly ambiguous, because they didn't use surnames then the way we (in the west) do now, but I think LNAB Bayley would best aligned with WikiTree practice.
Euroaristos/Magna Cartans/medievalists, can you confirm?
