Maria could have been made a minor character that pops up from time to time and Cragen could be consulted with from time to time.
It's like the writers are desperate for "shocking turn of events" and erase characters who can still be used, for keeping Olivia traumatized/sad.
Each of those samples were copy-pasted into an Excel sheet, which has the following columns: username, descent, genetic distance from the Samaritans, Samaritans' ranking in closest populations, source of information (links), geographic background.
Notes:
Also, before these six's inclusion, the palestinian muslims were at a genetic distance of ~5, but then were added an individual who's half Samaritan and their average got closer.
The German Jew recorded here is half Yemenite Jew, so back to note #1.
There are many individuals of mixture of 4 or 5 European Jewish communities that are below the 50% requirement of being a stand-alone bar/category and thus were calculated as a "European Jewish average".
The Cypriot Jew is only half of such descent, he is 25% Cypriot Non-Jew and 25% Canary Islander.
Five of the nine jordanian christians here are from a single family, whose maternal grandmother was an unspecified syrian christian from damascus.
All but one of the Yemenite Jews were mixed; but still half of their affinity comes from Yemen.
The Judean samples from the Roman era are imputations, scaled by ExploreYourDNA.com; it's not real science. I used them for fun.
The Libyan Jew presented here did not identified as such, sadly he just shared his genetic distance and ranking with me before deactivating. I found comments that referred to him as such, if that would be proven wrong, I will update this.
