I was inclined to think black holes held the rest of the galaxy in place (an incorrect assumption) but it seems they play little part because their gravitational influence does not extend very far at all.
So it is interesting to wonder what their part is in the scheme of things...they do not seem to be anchor points as it were... they are not to the galaxy what our sun is to our solar system in so far we orbit the Sun because of its gravity influence...the solar system does not orbit in the galaxy because there is a black hole at its center... so that is curious.

True, the orbiting stars are less to that black hole than the Earth is to the Sun. I was being pedantic. That is one of my special abilities. If you define the MBH as a star, and you seem happy to do so if the BH is of stellar mass, then our friend
Sgr A* and the many stars that dance attendance upon it are a multiple star system. There are quite a few papers on arXiv about SMBHs. They generally star close to the galaxy's centre of mass.
