Birth certificates (patrini)

Dallas152

This is my grandfathers birth certificate as well as his fathers birth certificate above, I though patrini column was meant to be godparents, can someone explain why the same name would be in both certificates 35 years apart?

Eppich Maria

1.     Maria, wife of Francis (?) Rybicki

2.     Rybaczuk, Franciscus

There may be a lot of repetitions of names in a family, even after 35 years.
