No, no need to apologize at all -- you're right to be asking these sorts of questions. I was just wondering if you have better information that could be added in.
In cases where I can't determine the source of information, I usually message the profile's manager and/or the person who created the profile. Michael Kesselring's profile was created by Tiffany Beesley Brock and is managed by Glen Ross Hitchcock, so sending a message to either of those people should at least get you going in the right direction.
