Modern Families

My older daughter's older step daughter is about  to marry a man with two young sons.

Will that make me a step-step-great grandfather?

If so, what responsibiliities, if any, are associated with this role?  What, if any, rights?

Younger daughter says i'll just be another great grandpa; but would not the actual great grandparents have some say in this? 

Each person used to have 4 great grandfathers, not 5.  But that was before, artificial insemination,surrogate motherhood, etc.
