Help with Certification for NYC Documents

I’ve hit a snag in my jure sanguinis journey and could really use some advice. I obtained the following records in Brooklyn, NY:

• My great-grandmother’s birth record in 1900 deceased)

• Her marriage record to my great-grandfather in 1926 (also deceased)

• Death records for her parents (1932 and 1933 respectively)

I sent these documents off to be apostilled, but they were returned with a note saying they need to be certified first. After doing some research, it seems I need to obtain an order from a New York court to certify them.

Could someone please explain in simple terms what steps I need to take to get these records certified? Is it as complex as it sounds, or am I overthinking it? (Btw i'm on the west coast if that makes any difference)

TIA!
