In Part 2 of my Darling ThruLinestm analysis, I’m looking closely at matches with wife’s maternal 2nd great-grandparents, Bernard[i] Trümpi (1844-1913) and Bertha (Koch) Trümpi (1862-1927).
ThruLinestm indicated that there are 3 (newly discovered) cousins who match Shirley through the Trümpi line.
J. S. Descended from Bebetta Trümpi
J. S. and Shirley share 15 cM of DNA on one chromosome, which is a very small amount.
ThruLinestm suggests that the connection is through great-aunt Babetta Trumpi. Babetta was the second of the seven children of Bernard and Bertha. Babetta also had another seven half-siblings from Bernard’s first marriage. She was born 9 Oct 1888, emigrated to the United States Oct 1905, and married Wilhelm Fuchs on 16 Nov 1906 in Winnebago, Illinois. They had at least eight children, one of whom was Walter Fuchs. Walter died sometime before 2006.
Through the tree of J. S., I learned that Walter married Katherine Welty and had children, one of whom was J. S.’s grandparent.
With the suggested tree, J. S. would be a 2nd cousin 2x (2C2X) removed. Genetically, a 2C2X should share between 0 and 261 cM, which is in the expected range but is a very low amount. DNA Painter suggests a 7.5% probability for this relationship.
L. C. Descended from Freida A. Trumpi
L. C. and Shirley share 112 cM of DNA on 7 segments. Much more in keeping with what I would expect from a 2nd cousin.
ThruLinestm suggests that the connection is through great-aunt Frieda A Trümpi. Frieda was the fourth of the seven children of Bernard and Bertha. Freida also had another seven half-siblings from Bernard’s first marriage. She was born 9 Aug 1895, emigrated to the United States in 1906, and married Adolph John Karch on 27 Feb 1913 in Chicago, Cook County, Illinois. They had at least five children, one of whom was Albert Adolph Karch (1913-1963). Walter died sometime before 2006. L. C. is one of Walter’s children.
Thus, the paper trail also suggests that L.C. and Shirley are 2nd Cousins. They share 112 cM of material across 7 segments, which fits within the range (46-515) expected for 2nd cousins, but at the low end (8.9% likelihood).
K.B. Descended from Freida A. Trumpi
K.B. and Shirley share 23 cM of DNA on 2 segments.
ThruLinestm suggests that the connection is also through great-aunt Frieda A Trümpi. I mentioned Frieda under L.C.’s relationship. Another of Frieda and Aldolph’s children was Elinor Frieda Karch (1914-1998). Elinor married John Patrick McCarthy and they had at least one child, Marcella Rae Whitmore (1935-1998). Marcella is K.B.’s grandmother.
Thus, the paper trail also suggests that L.C and Shirley are 2C2R. They share 23 cM of material across 2 segments which fits within the range (0-261) expected for 2nd cousins, twice removed, but again, at the low end (8.3% likelihood).
I find it interesting that all of these ThruLinestm connections include much less DNA than would be expected. All within norms, but all in the bottom 10% for the paper relationship. That makes me wonder if there might be some event that would reduce the amount of DNA shared significantly. This might be a good candidate for chromosome mapping. I have a “gut feeling” that I have something wrong and that Bernard had two wives name Bertha.[ii] If so, that Babetta and Freida’s descendants had less shared DNA than expected would make sense.
Finally, if you are a descendant of Bernard Trümpi (1844-1913) or Bertha (Koch) Trümpi (1862-1927), please consider testing with Ancestry DNA; it is an excellent genealogical resource, which may help you broaden your tree.

[i] Also known as “Bernhard” in some documents.
[ii] There is “oral history” that indicated that Bertha didn’t care for her stepmother, Bertha and that she never went out to California to see her. That suggests that Bertha Koch was a stepmother and that Bertha had a different mother, also named Bertha from her younger siblings. Bertha’s older siblings’ mother was Regula Stüssi who died in 1882, a year and a half before Bertha’s birth.
