Christopher Coleman is the dead-name of trans woman composer now named of Rachael Coleman. Not sure you how you want to handle this for redirects or bio. Would be similar to Wendy Carlos. Coleman's site are still reflecting "Christopher"
Create a redirect from Christopher to Rachael. And change the gender in the Categories and the bio. (dead-name?)
Note that the records for Post-Apocalyptic, Snake Oil and Something Old are pretty messed up. If you can get to them before I, it would be helpful.
