I want to review ED 15-12 sheet 31 in Island County, Washington. How can I do that?
Oops - my mistake. I was on sheet 29 instead of 31. You're back to having to be lucky at this point.
You cannot edit directly from the image. You have to get into the 1950 Census review screen to be able to review and edit any information that will be retained/shared by FamilySearch. The link is below. The interactive map allows you to choose a state that you want to work with. You can also specify a surname that you want to find in the census. However, since there are many people that share the same surname, the chance that the computer will give to you the specific record for review is not great unless you review entries for many people with that surname in the state of Washington.
As mentioned previously, once the index has been initially reviewed and the indexed version made available on FamilySearch, you will be able to look up your record in the census and edit the relevant information.
At this point you would just have to be lucky. Although the process may continue to evolve, the system does not currently allow you to pick your area of review to that precision. You could try specifying the surname of people on the page and see if it would send you to that page. I tried specifying the state of Washington and the surname of Limback (it seemed a somewhat unique name that was on the page) and the system sent me directly to that page that you requested. You could try that - though the computer could randomly assign it to some other person between when I tried it and when you try it.
The state of Washington is currently only scheduled for Review Names - and that goes pretty fast. The capability to Review Families is much more detailed and takes more time. The Review Families will probably be an area where you will want to try your luck in getting to that page.
It should be noted that even after the initial review, processing and publication of the indexed material, the ability to edit the indexed information will be available in case errors need correction.
I have the image up. I want to edit my own name. I cannot see how to edit my name. Is that possible at Family Search?
Interesting. A couple of weeks ago I found my family at NARA. My last name was indexed wrong, but I did not fix. I don't remember how they had it spelled. Thank you for your suggestion.
