I see you're experimenting with disambig pages. Just for some context, we used to have disambiguation pages but deleted them all in favor of search results pages or "other uses" sections on the most commonly viewed page.
I don't have a strong opinion, and I'm happy to have you try as many things out as you like.
In this case it seemed to be the best solution, especially since Alex was a redirect to Alex Hanson, which is just incorrect. Or you could delete it, in which case searching for "Alex" would produce about 40 results (but not Alexander!).
