All My Foreparents: Imperfect Triangulation
http://allmyforeparents.blogspot.com/2015/03/imperfect-triangulation.html
ENDOGAMY: One Family, One People. Wednesday, March 18, 2015. While examining the autosomal DNA results of Ira and Steve on GEDmatch, a curious thing turned up. Ira and Steve are second cousins, great-grandsons if Isak Pikholz of Rozdol and his wife Toby Blum. In the course of my analysis, I saw the following on chromosome 7. Ira and Steve have a match of just over 66 cM, as represented by the orange bars. In order to confirm the GEDmatch numbers, I did a chromosome browser for Esther. The bar graphs look...

All My Foreparents: January 2015
http://allmyforeparents.blogspot.com/2015_01_01_archive.html
ENDOGAMY: One Family, One People. Wednesday, January 28, 2015. Small Segments (and Endogamy). The issue of small segments. When we compare autosomal matches on the basis of individual chromosomes, there is a natural tendency to concentrate on the larger segments. If you match someone on 30 or 40 centiMorgans (cM), it is clearly a good match. Small matches of one or two cM get overlooked - often deliberately. After I raised this question several times at the GRIP course. FamilyTreeDNA's chromosome browser...

All My Foreparents: Getting the Y-Chromosome Right
http://allmyforeparents.blogspot.com/2015/03/getting-y-chromosome-right.html
ENDOGAMY: One Family, One People. Sunday, March 1, 2015. Getting the Y-Chromosome Right. It is axiomatic that all the Pikholz descendants from Rozdol are from a single couple, Pinchas and Sara Rivka, whose youngest known child was born in 1818. The problem has been that Robert (who is traceable to Pinchas and Sara Rivka as a fourth-great-grandson) and Gadi (traceable to his second-great grandfather David ben Isak and Feige, who was born about 1823) do not have matching DNA. It is possible that the co...

All My Foreparents: Matching Sandee
http://allmyforeparents.blogspot.com/2015/03/matching-sandee.html
ENDOGAMY: One Family, One People. Monday, March 30, 2015. I manage sixty-eight family autosomal kits on GEDmatch, with six more either in the lab or expected there soon. It is no wonder, then, that I get more than a dozen inquiries a week from people who find matches. Many have very little information and others have some meat on them. These range from:. Dear Mr. Pikholz,. I have a match with you on GEDmatch. Can you tell me how we are related? My families ancestral surnames are: [redacted]. Most people ...

All My Foreparents: December 2014
http://allmyforeparents.blogspot.com/2014_12_01_archive.html
ENDOGAMY: One Family, One People. Sunday, December 28, 2014. How Many Husbands Did Ethel Pikholz Have? When the Pikholz Project first began acquiring records from the AGAD archives in Poland, we ran found Skalat birth records for Ettel and Chaje Ester Pikholz, daughters of Aryeh Leib Pikholz and his wife Sara Kreisel. (We later learned that Sara Kreisel's maiden name was Glisner.) Ettel was born 9 January 1860 and Chaje Ester 6 April 1862. We next find Ettel sailing to the United States. The 1900 census ...

Louis Kesslers Behold Blog. Writing Freeware (Double Match Triangulator). Sun, 17 Jul 2016. Most people might think releasing a freeware program is easy. Just write it and make it available. Right? Well, there’s a bit more in it than that. When I came up with the idea for Double Match Triangulation of autosomal DNA using the chromosome match files produced by FamilyTreeDNA. So at that point, just a few little things to do:. 1 Blog about the technique. 2 Get a few sample files from people. So I can test it.

ENDOGAMY: One Family, One People. Sunday, October 26, 2014. A Look at the Matching Segment Search (GEDmatch). Last week, for the first time, I wrote about GEDmatch. Just in time for the launch of their four new subscription tools which they call "Tier1. Kitty Cooper has blogged about the triangulation feature. And Blaine Bettinger has blogged about a tool they call Lazerus. Which recreates the DNA of ancestors based on the tests of living descendants. Miriam and my second cousins - a directed search.

All My Foreparents: Sam's Daughter and the (Isak) Josef - Mordecai Complex
http://allmyforeparents.blogspot.com/2015/03/sams-daughter-and-isak-josef-mordecai.html
ENDOGAMY: One Family, One People. Sunday, March 8, 2015. Sam's Daughter and the (Isak) Josef - Mordecai Complex. Early in our research on the Pikholz families, Jacob Laor obtained a copy of the marriage record of Berl and Dwojre Pikholz, with the help of Alex Dunai. The document was from 1887, but was obvously just a formality, as the couple had been having children together since at least the 1860s. The family structure appeared thus:. Everything pointed to a fairly close relationship between the two co...

(I have discussed her here. In brief, my great-grandmother died probably in her late thirties and we nothing about her except that her father was Yehudah and that he was a Levi.
