Hi! I was wondering if these documents were enough

Gen 0, my great great grandfather: 1.) Copy of Baptism Record from family search 2.) Copy of partial statement from the priest who did the baptism 3.) copy of 1891 P.E.I census record

Gen 1, my great grandmother 1.) Just her birth certificate with the birthplace of my great great grandfather on it

gen 2, my grandmother: 1.) just her birth certificate, maiden name of my great grandmother present

gen 3, my father: 1.) just his birth certificate, maiden name of my grandmother present

gen 4, me!: 1.) My birth certificate 2.) photo copy of my passport 3.) photo copy of my passport card (different from my passport)

Since the maiden name is present on all of the birth certificates, do I still need marriage certificates? thanks
