The Waltham forest Archives are based at Vestry House Museum in Walthamstow. Their web page is here:

Waltham Forest Archives and Local Studies Library

The Archive is the Diocesan Repository for Church of England registers of churches in the Waltham Forest Deanery, and holds records of Waltham Forest and the predecessor councils of Leyton, Walthamstow and Chingford.

This page shouldn't be necessary, but Waltham Forest doesn't see a problem renaming pages for key services like the archives and leaving no landing page in the original location, as they did in 2016 invalidating everyone's links. Further, onbeing notified of the problem, WF IT refused to do anything about it. This page is here insurance case they do the same again.
