As promised, a brief update on what is, and is not, available on Ancestry in indexed form for Norfolk and Suffolk.
Suffolk has gone from nothing to being very nearly indexed in the last week or so - if you search for people in the 1911 England Census who live in "Suffolk, England" and restrict to this place exactly, you get 381,265 results from a population at the time of approximately 383,000.
Norfolk meanwhile, shows 41,982 indexed residents out of a total of approximately 489,000, suggesting that it has stayed the same since my last update. However, those of you who have been residents long enough (unfortunately it was more than a decade before I was born!) will remember the boundary changes in the east of both counties following the Local Government Act 1972 which came into force in 1974.
The following modern-day Norfolk parishes were in Suffolk before the changes and therefore are already searchable on Ancestry:
Fritton, near Great Yarmouth (not to be confused with the other Fritton!)
If you were wondering about Gorleston, it was already in Norfolk by 1911. The NRO have a leaflet all about Gorleston, Southtown and Runham Vauxhall and their various administrative histories here: http://www.archives.norfolk.gov.uk/view/NCC098519.
As ever, hoping this is useful. I should also point out that the full 1911 census is already indexed on other websites, including www.findmypast.co.uk, www.1911census.co.uk and www.thegenealogist.co.uk. Non-indexed images are of course still available at Ancestry, allowing you to browse by parish, and you can also still use the trick in the post below to skip from summary book to census image.
