Hi, I agree most of this data is not needed. A lot of it is a personal choice. Here is what I choose to retain when I clean up profiles like this one:-
- I keep the hyperlinks to the Ancestry personal family trees. Sometimes the links work, and if you have an Ancestry account, a future reader might want to see them.
- I retain references to the title of general sources sometimes seen on Ancestry, eg "US and International Marriage Records"). Again, it is not accessible but useful for people to know the underlying "source" of the data.
As Magnus said, if a profile is completely reliant on Ancestry material, it should be considered as unsourced unless the person has been able to provide supporting information as to where the record could be found. For example, this profile says "St Matthew Parish Records". Of itself, it tells us nothing, so its unsourced. However, if the record had said "St Matthew Parish Records, accessed on Ancestry, originals kept at the Berkshire Public Record Office, Volume XXX, page XXX" then my view is different, it is sourced. Note I have not used "Evidence Explained" source descriptions, this is just shorthand.
So, in a nutshell, I would not delete 100% of the Ancestry data, I would keep the hyperlinks to personal trees, and descriptions of Ancestry record sets if included, but delete the rest.
