Saint Juan Diego Parish

in the Archdiocese of St. Louis

We're still populating this registry. The data-quality score on each entry shows how complete and well-sourced it is today; many are sparse for now, and the scores climb as we verify and enrich the data.

Contact

Address, phone, email, and website are sourced from the parish's diocese website, the parish's own site, and public registries (Google Places, IRS BMF).

website_status flags broken pointers (dead_domain, parked_domain, aggregator, etc.). Strike-through indicates the URL no longer resolves to a working parish website.

Identity

The registry ID is permanent. It survives renaming, merging, closure, and address changes. Reference it externally and it won't change.

Year founded and religious order are extracted from diocese-website history blocks where available. Coverage is sparse today; expected to fill in over time.
