Here is how much I share with various TA members and some other people.
All comparisons posted below have been made with the same settings:
Minimum threshold size to be included in total = 500 SNPs
Mismatch-bunching Limit = 250 SNPs
Minimum segment cM to be included in total = 1.0 cM
People who are not TA members are marked as * (this includes Northener):
*Northener - total 58.8 cM, largest 3.9 cM
Noricum - total 50.7 cM, largest 3.9 cM
Slavic Italian - total 48.7 cM, largest 4.7 cM
*Linda Steinbach - total 48.2 cM, largest 4.0 cM
Mlukas - total 46.6 cM, largest 9.8 cM
Silesian - total 45.2 cM, largest 4.8 cM
Enflamme - total 43.8 cM, largest 4.1 cm
*Amerijoe - total 39.2 cM, largest 5.0 cM
Kazimiera - total 37.6 cM, largest 2.8 cM
Jackson - total 36.9 cM, largest 3.7 cM
Kriptc06 - total 30.6 cM, largest 4.0 cM
Cniva - total 27.4 cM, largest 4.5 cM
Sikeliot - total 24.7 cM, largest 3.7 cM
Potentia - total 20.8 cM, largest 2.3 cM
KnowledgeIsKing - total 10.2 cM, largest 2.9 cM
*Rhea Tannenbaum - total 9.4 cM, largest 3.2 cM
*Clare Ciszewski - total 7.6 cM, largest 7.6 cM
Myth's mom - total 6.3 cM, largest 5.1 cM
CrazyDaisy - total 3.4 cM, largest 3.4 cM
Ilma - total 2.7 cM, largest 2.7 cM
Norka - total 1.5 cM, largest 1.5 cM
Zoran - total 1.2 cM, largest 1.2 cM
Dominicanese - total 0.0 cM, largest 0.0 cM
Surprisingly, I share the most with Northener - who is a Northern Dutchman from the Netherlands. He is registered on Eupedia and on Anthrogenica, but not on TA (as far as I know).
Linda Steinbach is a Prussian German with some ancestry from my region.
Rhea Tannenbaum is a Prussian Jew with some ancestry from my region.
The reason why I share segments with Northener might be our ancestral connection.
It is possible that one of his ancestors and one of my ancestors came from this area:
But nothing is certain about it. And that could be only few centuries ago, not recently.
I share the largest segment with Mlukas, but more of total cM with some others.
The second largest segment I share - 7.6 cM - is with a Pole from my region.
