Searching for double cousins

[Mattkmmr]

@bgee

It found 242 cases of double cousins. That seems high

Yes much more than my database. I have only 20 cases.

@bgee

Since is looking only at first cousins, an obvious extension would be to look for double second/third/Nth cousins.

I’ll add double second cousins and also try for higher degrees, but I think those get very very rare.

@bgee

I did a quick look for duplicates and did not notice any. Does the code know how to leave out duplicates?

Yes it should avoid duplicates, but let me know if you find any duplicates.

@bgee

Other suggestions: An option to set the display format of the name. That is present in most other reports so should be easy to add. An option to set how the list is sorted, if it is sorted at all.

Both are good ideas. I’ll add them.

@PLegoux

I’ve that couple (Pedigree collapse, implexe in french) which seems to me to be relevant to that report but I can’t find it in the report:

Your couple (green) is not double first cousin, since the parents are from three different families, while double cousins are only from two families and pedigree collapse is not checked in this report.
