The correct way is to go to the FINCH parents and add the two sisters.
Then go to the EVERETT parents and give them the two sons (it should be already correct when we see your report example).
Then create the corresponding wedding.
Your data are correct.
Now, the trouble is : How to display all in only one tree representation.
Sorry for you, this is not possible with Ancestris.
All the reports will duplicates the information.
Except for the graph module.
In this display, each individual is displayed only one time even it could be appears several times in the tree.
