So far we know of 10~ D families
- Monkey
- Gol
- Portgas
- Nefertari
- Trafalgar water
- Jaguar
- Clou
- Davy
- Rocks kinda
- Marshall kinda
Out of those 10~ only 5 of the families have living descendants
- Monkey d Luffy Dragon and Garp
- Nefertari d Vivi
- Trafalgar Water d Law
- Jaguar d Saul
- Davy Rocks Marshall D Teach
Sabo obviously seems to have strong ties to people with the will of D and is pretty much carrying on ace’s will through himself. I know people hate his similarities to ace already but him inheriting his name could happen. Specially the Portgas side not Gol
Robin is also someone who has lots of ties to people with the will of D. With her basically inheriting her mother’s and clovers ambitions of learning the true history of the world she’s basically their successor. Clover specifically being a mentor figure for her. So her inherenting his name as well could be possible too imo if not literally at least figuratively
Then we got Shanks the man raised by Roger and tasked to carry his will despite knowing he isn’t the joyboy. Roger basically being his real father despite not being his biological one similar to Sanji’s situation. He even inherited his fighting style and hat. Him referring to himself as Gol rather than Figarland makes sense
Also if teach decides to go by either Rocks or Davy we’ll have 3 emperors that represent the main 3 D’s of the old era
