Recurring people not visible on exported descendant graph

Help
1

Hi! I’ve started building my family tree on Gramps two days ago, and I love it. I did come across an issue. There are some people on my tree who belong on multiple branches of the tree, due to cousin marriages. When I export a descendant graph to PDF, they are visible only on one of the branches, even though they are registered as children on both. Is it meant to do that, to save space on the graph? And is the (only) solution to enter them twice, as a new family?

I’m using GRAMPS 5.1.6 on Windows 11.

On the Report Options there is an option to show duplicate trees. Check this option and your full tree will be displayed.

Thanks GBaynes. I took a look, but unfortunately I can’t find such an option under Report Options. To be clear: I’m on Gramps → top bar → Reports → Graphical Reports → Descendant Tree → Report Options (1) and (2). I only see options regarding:

  • Report title
  • Scale tree to fit
  • Name format
  • Living people
  • Years from death
  • Translation
  • Date format

I thought that you were on the Text Reports/Descendants Report. That report gives you an Indented list.

Diagramming the results of consanguineous marriages is a special case. One that is not currently handled by this Report. You would probably need to file a Feature Request.

I created a test case (using the Example.gramps tree) by merging the spouses of 2nd cousins (Barry Joseph Garner & Barbara Jo Garner) into their respective cousins. (And trimming out some of the excess offspring to simplify the charts. Also, I turned off display of much of the rendering of detail to simplify the diagrams too.)

When charting the offspring in the Descendant Fan Chart, it looks like this:

Since Barry Joseph Garner is the cousin descended of the elder child in primogeniture, his offspring is are fully diagrammed in his arc of the fan chart. But he appears as a Greyed out segment in his wife’s arc… to indicate he is already diagrammed elsewhere.

The Descendant Tree addon Graphical Report completely omits a second listing of Barry as his cousin’s spouse. (That would be a feature request.) But there’s also a bug in that direct descendants are supposed to be Boldface font. It looks like it took the expedient of putting all spouses in plainface.

Meanwhile, the Family Tree graphical report addon shows the Duplicate offspring but has no indication that they are duplicated on the diagram.

Another proposed diagram has a more of a deep dive into diagramming inbreeding:

How about the Relationship Graph?

Dear @emyoulation and @GeorgeWilmes,

Thanks for your replies to my question! The family plugin indeed did the trick for me. The fact that it doesn’t show that they are duplicated is not a problem. And @GeorgeWilmes the relationship graph indeed displayed all descendants as well. Rather than duplicating the descendants, it shows them only once and connects them in a very clever way. The only downside is that the graph overall looks a bit complicated, but I like the result nonetheless. Will play around with it :slight_smile:
