Split database (Tree) into 4 parts at grandparent lines?

[derFred]

Gramps Version 5.1.5.
OS Linux

Hi - as I said before …
I am a complete beginner

That’s why I just got started and now working with > 300 people.

Now the question for me is

1. whether I can split the database
   and if so
2. how do I divide a db into 4 db, i.e. a branch for each of my grandparents.

To be more precise 4 separated db.

Is that possible at all?

[DaveSch]

It is possible.

But I (and many others) do not recommend it.

Besides keeping track of and updating the common families in two or all of the branches, you would also be maintaining 4 set of place hierarchies, sources and citations.

When needed, if you want to run a report on any one of the branches, that can easily be done from the single database.

But, if you want to proceed, I recently showed how to create a series of filters to identify all of the relatives of a person.

Report to identify persons who are not direct ancestors

Welcome Probably the best way is to create a set of filters to select your family, tag them, then decide what you will do with any people not tagged. In the People Filter editor (in a person view, menu >> Edit >> Ferson Filter Editor) create a set of filters. Filter 1 Ancestral filters > Ancestors of <person> Filter 2 Descendant filters > Descendants of <filter 1> match General filters > People matching the <filter 1> Set the Options At least one rule must apply. Note: adding the first…

You would use each of the grandparents in the filter and create an export of that person’s branch.

Use the Gramps XML export, use the with media option if each database will have its own media folder, select your branch filter in the People filter (it will be the last filter I demonstrate), and select the References filter Do not include records not linked to a selected person.

Import these exports into a new empty tree and you will have new databases for each grandparent.

@ DaveSch many thanks for the quick reply and the filter set.

As I am still a complete beginner, I will of course follow your advice and not split the db into 4 parts.

Is there a “repository” here at Gramps for such hot tips, so that I can find your contribution again if necessary, or should I copy the instructions here at my place.

Thanks again.
The db will remain as it is for now.

Discourse is searchable for topics, but many topics are recurring. Visiting regularly will teach you many ways to get the most out of Gramps.

Most activity is now here on Discourse but earlier activity was on a mailing list archived here…

There are a few tagging categories for threads here and on the wiki. The “Hacks” tag here and the “How do I…” category on the wiki are worth exploring.

Start with the ‘hack’ thread: What patches are 'vital' to your use of Gramps 5.1.x?

Hint: use the Advanced Filters (click the magnifying glass) here on the Discourse to search by ‘Tag’. Click on the Categories hotlink in the footer of wiki pages for an index of Categories.
