I assume you're looking for the name change info prior to drivers licenses being issued. This occurred in our family in Pennsylvania mid 1700's from Erdle to Artley.
I didn't look for name change records in court records because I didn't think I'd find anything.
Each family member changed their surname over time. Sometimes I'd find a person with the Erdle surname on the Census records and their tombstone would have Artley as their surname.
I think you'll find the same situation. Successful Searching!
