While an answer to this may be possible, it's beyond the scope of WikiTree, We're just a repository for information specific to Genealogy. Your question is a good question, just not something we're set up to handle.
Names do change over time and if a name change is covered here and so noted, that change can be traced down. A lot of names have been changed. My grandmother was a Chilcoat, her grandfather was born a Chilcote, and his ancestors were Chilcotts or Chilcottes. Its not as major a change as yours, but it's hard searching when you don't know the correct spelling.
