Hi Jesse (and others following this thread),
looks like we're really onto something. I've compared your kit against my father and his two sisters. We do have indeed 5 segments where you match with all three siblings and 7 where you match two of them:
Matching all 3:
Chr Start Location End Location Centimorgans (cM) SNPs
1 186,155,499 190,024,731 2.0 621
2 196,434,716 199,488,869 2.3 530
3 3,255,819 4,752,434 5.0 582
10 18,744,782 20,322,983 1.3 511
12 20,835,693 21,749,447 1.5 531
Matching two of them:
2 159,369,731 163,124,693 2.2 684
7 12,536,902 14,346,084 3.1 623
7 32,424,097 34,959,160 2.3 560
8 50,415,911 53,537,958 2.6 526
8 91,246,126 94,427,906 2.0 522
16 78,075,910 79,619,328 3.2 602
18 22,707,729 23,892,757 1.4 586
All of them were FTDNA kits compared against each other, so we have 674k SNP's coverage for best results.
FYI - I used GEDmatch (not Genesis) with 500 SNP's and 1 cM minimum threshold in the 1:1 comparison.
Kits to match against are (paternal side):
T443643 (Juergen Basso)
T231565 (Ingrid Margarethe Dinger)
T080473 (Ruth Geise)
All three of them are my paternal line in case someone else wants to go ahead with a similar analysis.
As we're trying to identify deep Palatine ancestors DNA I also compared your kit against my mum, her sister and her brother. Again, 3 matches with all three of them and 7 matches with two of them:
Matching all three of them:
3 84,761,773 89,485,137 1.7 744
8 26,335,782 27,532,734 1.7 561
12 20,685,192 21,749,447 1.8 607
Matching two of them:
6 31,028,936 33,010,561 1.6 2,694
7 121,738,201 125,195,173 2.5 662
8 17,627,431 18,551,815 2.0 551
12 25,556,120 27,470,013 2.6 576
14 58,913,951 61,565,977 1.7 510
14 62,470,539 66,990,924 2.9 833
16 78,735,157 80,294,248 4.2 633
Kits to match against are (maternal side):
T337227 (Christel Schink)
T604749 (Marieta West)
T028826 (Manfred Cremer)
One of the segments (chr 12 20,685,192 - 21,749,447) is shared by all parties (both all my 3 from my paternal and all 3 from my maternal side). It has 530 to 610 SNP's in common. Seems to indicate that we've found indeed some deep Palatine connections here.
Spurred by this I went on to analyze where in the wider Palatine region (for me that's more the Eifel and Hunsrück) my ancestors are coming from.
Here's a map of my ancestors in the region:
Maps of Palatine (Eifel-Hunsrück) ancestors
My maternal side ancestors are coming from what is in the lower right of the previous map, I zoomed more in with this one (cities are Ravengiersburg-Rayerschied-Dörrebach-Stromberg-Schöneberg-Spabrücken-Waldalgesheim-Waldhilbersheim-Wallhausen):
Hunsrück region (maternal ancestors)
For my paternal ancestors it's the Eifel region, again a zoom in of the first picture (Hirten-Weiler-Thür-Ochtendung-Plaidt-Lonnig) :
Eifel ancestors (mostly paternal side)
As for that DNA segment which seems to be on both my maternal and paternal side it all points to Weiler (near Hirten) in the Eifel region where I do have a Maria Waldecker (married Schneider) WikiTree profile of Maria Waldecker from my maternal side who seems to be related to the Waldecker from Ochtendung (my paternal side). Both villages are anyway only 23 km apart as you can see in this image:
Route from Weiler to Ochtendung
Lastly the ancestors of Johann Castor Adams WikiTree profile of Johann Castor Adams from Hirten (who is a descendant of the above Maria Waldecker). His son Nicholas Michael Adams WikiTree profile of Nicholas Michael Adams emigrated to the US in 1851 and help found Johnsburg, McHenry County, IL - many ancestors are DNA matches!
Ancestors of Johann Castor Adams
If you're somehow related to this famous Adams family (pun intended) then that would probably explain the DNA matching segments.
Lastly my main locations and surnames in the Eifel & Hunsrück region:
Paternal side:
Kobern (CONTERMANN or KONDERMANN)
Lonnig (KONTZ or CONTZ or CONZ, RÜBER)
Ochtendung (MONREAL, BARTZ, BERESHEIM, KOHNZ or CONTZ or CONZ, OSTER, ROHM, WALDECKER, RÜBSAM, NÜRBURG)
Plaidt (BARTZ, WEIBER, WEILER)
Thür (HALBEDEL)
Weiler (WALDECKER)
Maternal side:
Dörrebach (SONNET, DUPOND)
Hirten (ADAMS, BANTHUS)
Ravengiersburg (KNICHEL, WINCK, BERES)
Rayerschied (BERRES, KESSELER)
Schöneberg (FREISEM)
Spabrücken (FREISEM)
Stromberg (DUPONT, ORBEN, FREISEM)
Waldalgesheim (FREISEM)
Waldhilbersheim (DULIUS or TULLIUS, RÖHSER)
Wallhausen (DULIUS or TULLIUS, KNICHEL, DUPONT, BARTH, RÖHSER)
Weiler (ADAMS)
Looking forward to see if others can identify more deep Palatine ancestral segments!
