He's not part of the Capp family anymore seeing as Miranda (who should inherit the family and stuff) is still on Goneril's custody. It would be like if Blair Wainwright married Mortimer Goth, became Blair Goth, and then had a child let's say Frazer Goth. Then Blair and Mortimer divorce. Mortimer remarries with Bella and Blair ends up with Ethan Bunch, they marry each other, Blair decides to keep the Goth surname but change the spelling into Goethia for her, Ethan, and Frazer, and then Blair Goethia and Ethan Goethia have a child named Lilly Goethia.

It would not work like that, he's not part to the Capp family anymore and does not belong to Goneril. I always change sims names back to a feasible maiden name when they divorce in TS3. Or just when a spouse dies. (i say feasible b\c TS3 sims usually do not have family trees, except for the "returning" ones.)
