Theory JayGarcia was the original ruling family of Germa

[Monkey D Theories]

Germa is a scientific kingdom

Saturn is the god of scientific defense.

What if the reason for this is because originally, the JayGarcia family were the kings of Germa. Then they went off with Imu to create the WG, subsequently leaving Germa in the hands of the Vinsmoke.

The JayGarcia meanwhile remained scientific scholars even in Mariejois, leading Saturn to eventually become the god of science.
