In the section under OFFICE the only genealogy program is GRAMPS which I do no care for. I have recently come across a program called ancestris which I find quite good and was wondering if it would work in the Boutique. it is at ancestris.org and it comes in a deb package and I believe it has a PPA. Thanks for your consideration.
This sounds quite interesting.
Sadly there is no apt repository, PPA or snap so it can’t be added to the Boutique 
On there website it looks like they have a PPA. See below:
Ubuntu
This tutorial describes the installation of Ancestris (K, X, L, U) buntu 12.04, 14.04 and 16.04.

Step 1 : You can add the PPA to your system with a single line in your terminal. Open a terminal and enter:
sudo add-apt-repository ppa:ancestris/ancestris-9-0
Just copy and paste the above line in a terminal.
To open a terminal, go to “Applications” then “Accessories” and then you’ll find “Terminal.” if not le forum d’Ubuntu, we explain how to do).
Step 2 : Update your repository
In the terminal, enter :

Then, everything will be automated. You’ll be notified each time a new version is available.
