Consolidating Inputs/Tags

Is there an etiquette to consolidating inputs/tags in a platform. For example:

15 people say they work at Washington, Adams and Jefferson in their profile and another 15 people title their work as Washington, Adams & Jefferson LLP

If the latter is correct and we would prefer all users to display the same title, is it safe to just merge the titles? Provide a notification of change? Provide the option to change? Any ideas on this would be greatly appreciated!
