Existence of records in Alswede

Jenealogy

From FamilySearch, I see:

Taufen, Heiraten, Tote 1646-1688 "Geschichtliche Ereignisse" Heiraten, Taufen, Tote 1689-1730

The reality is that the marriages don't start until 1670. Checked on Archion.de and they have the same records.

Question: Is there a way to find out if there are marriage records from 1646 to 1670 for Alswede OR if not, what other parish would they have gone to for marriages during that time period?

Thanks so much!
