Do you think Madara was the only one who granted rinnegan by him self? Just no transplantation.( except eternal mangekyou sharingan). Tobi did let his eye transplanted...

who else? Except rikudou.

elder son?

Yes, because nagato didn't awaken it, and neither did tobi/obito. Which leaves only madara

elder son?

Elder son was only uchiha, half rikudou. You need both halves to awaken rinnegan
