The chart below caught my eye as I have London Ancestors. I have not tried to research those ancestors, but with this guide I may give it a try. Thank you to EOGN for highlighting this Guide from the FamilySearch Research Wiki.
In celebration of the London 2012 Olympics starting this week, FamilySearch is pleased to announce a new online guide to tracing London ancestors. The guide has been published in the FamilySearch Research Wiki.
Features include articles on each of London’s 109 historic parishes loaded with descriptions of records available online at major websites Ancestry.co.uk, British History Online, BritishOrigins.com, FamilySearch.org, FindMyPast.co.uk, TheGenealogist.co.uk, Google Books, Internet Archive, London Lives, and ParishRegister.com among others.
