Bee, as I'm assuming you now have a licenced copy of FH6 rather than using the trial, did you try using the "Change Any Fact" plugin that was suggested on FHUG to resolve the Census sentence issues? It will change any non-standard facts to standard ones, so that you don't get "experienced" in the wording of sentences in Narrative Reports.
How many individuals do you have in your file? I'm just thinking if its a large number, it seems a lot of work to just remove and then re-add them, although that is one path to follow.
In the case of the Census facts that were imported from FTM, if you look at the "Facts" tab on the right of an individuals record page, do they show a date in the date column or is the year showing in the Fact name column instead?
If you're not sure what I mean, if you take a look at my first post and the second attachment on it, you'll see a list of dates with Fact names against them. That is the view I'm referring to just in case I'm causing any confusion. Its the second tab on the right hand side of any Individuals record in Family Historian. I see that my first attachment on that first post was too large to show completely on RC but if you click the file name and open the attachment, you should see what I mean if your view is different.
The "Change any Fact" plugin won't work if the date isn't showing in the date column but there is another plugin that will change the name of Census facts which are named, eg. 1841 Census, to just Census and add the full date to the date column for these facts.
Hope I've worded this OK.
On the subject of Census facts entered via Ancestral Sources, which I'm assuming was used for the John Pritchard example in your first post, you will see several Facts with the same date as the census, one being for occupation. If you don't want these, you can just click on them and click the red "x" to delete them. You could add the occupation details to the note section on the main Census fact (the one that shows where they were resident). If you look at the attachment on my second post on this thread, it shows a Census Fact highlighted with details in the note section at the bottom. The note section would be a good place to add any details such as occupation if you don't want a separate Occupation Resident fact.
If you include the occupation details on a Census entry within Ancestral Sources, it will create a separate Occupation Residence fact for the date of the census. I have queried why this happens but was told it was the only way it could be done.
That is why I now do not include occupation details when using Ancestral Sources but when the details have been added by Ancestral Sources to Family Historian, I go back and add the details manually to the note section for the relevant Census fact.
I hope this makes sense, let me know if it doesn't and I'll try and word it differently. I know what I mean even if nobody else can understand what I write.
