London Compiled Genealogies
Boyd's Inhabitants of London and Family Units (1200-1946) groups thousands of Londoners into families. The entire collection is available at the subscription website Find My Past. Much of the collection has been converted to a lineage-linked database and annotated by FamilySearch, see: Community Trees.
