how to combine many author pen names

https://en.wikipedia.org/wiki/Susan_Morgan

This lady had 5 pen names. There's nothing on LT under her actual name. I don't even know where to begin in bringing together all these names.

You can combine the unsplit authors, and then alias the subauthors on the split pages to the combined author page.

In other words, in this case you would combine Sophie Danson, Valentina Cilescu, and Anastasia Dubois, and then alias the works of Sue Dyson (1) and Zoe Barnes (2) to the resulting page.
