I started a reply but I can't find where it saved my draft.
If I can attach two repositories to a single source, that will help with the identical databases. There are cases where Ancestry refers directly to Familysearch to document the database; clearly the same source.
I am pretty new to Family Historian so let me outline a scenario, which will also help me think it through.
Long time ago, I got films from Familysearch for my Norwegians and Germans. Familysearch catalog organized them by parish register, and I cited the film number along with the register name, date, page, year, item number, etc. I didn't transcribe them. It was difficult work, going back and forth from archaic Norwegian to modern English.
Familysearch at the time had some abstracted indexes that were not tied to images; those indexes are now available at Familysearch and Ancestry in a separate database from the images.
The source of the Familysearch films is the Norwegian Digital Archive, Digitalarkivet, which has its own reference numbers but the same titles as Familysearch.
Ancestry or possibly Familysearch digitized the films and Ancestry combined the indexes into one large database. The indexes are different from Digitalarkivet's (you can't enter the same info and find the same record). Ancestry serves these up as hints, not realizing one citation is equivalent to another. Because of the difference in repositories and formats, the citations differ.
Here is a citation I wrote to Digitalarkivet assets (be kind, I was a beginner then):
"Norway, Sogn og Fjordane, Gloppen, Parish register (official) nr. A 7 (1827-1837)", browseable images, Digitalarkivet, URL
https://www.digitalarkivet.no/en/source/11429: 4 Dec 2007, Cathrine Olsd., no. 8, Death and burial records women 1834, page 208, viewed 12 Mar 2012, citing Statsarkivet i Bergen.
Ancestry's citation for the same record:
The National Archives of Norway-Arkivverket; Norway; Church Books 1815-1960; Reference Number: SAB/A-80101/H/Haa/Haaa/L0007
Source Information
Ancestry.com. Norway, Church Records, 1812-1938 [database on-line]. Lehi, UT, USA: Ancestry.com Operations, Inc., 2020.
Original data: Kirkebøker 1812-1938, Arkivverket, Norge.
The Reference number is the accession info at Digitalarkivet, and you can locate my title at Digitalarkivet, but Ancestry doesn't give the parish name or date, and this "original data" is the entire series, not a single film.
What I would like to do is two things. One is to tie the three repositories together--Ancestry and Familysearch to Digitalarkivet. I'd like a quick, easy way to do this once I realize I have the same record in two or three places. Digitalarkivet is the source of the source but working through the Norwegian to find the source reference is more work than I want to take on.
Second, automatically (if possible) turn off hints for material I already have. I don't want to re-find someone I'm not otherwise updating.
Perhaps a key is that I'm not "done" with these films. There were many items I didn't find the first time through the films, and I read Norwegian better now, so I can't just say "done" and never look again.
Have I overthought this? What would a good workflow be?
