Researching Genealogy Using Genetics

Much of this information is from Bennett Greenspan and the folks at Family Tree DNA.
I encourage you to participate with them because the larger the database of people tested
the more likely it is that useful matches will be identified from the data. 

John D-H Male Line 
(Y-DNA)

The idea behind this analysis is to find men with an identical or a very close match of 25 specific DNA sequences located on the Y chromosome.  In general, males have one X chromosome and one Y chromosome.  Females have two X chromosomes. 
This analysis requires an unbroken, all male chain of ancestors.  An identical match indicates that it is likely there is a shared male ancestor. 

John D-H Female Line (mtDNA)
The idea behind this analysis is to find men or women with an identical or a very close match of certain DNA sequences located in their mitochondrial DNA (mtDNA).  mtDNA is passed from the mother to either sons or daughters.  Fathers do not pass on their mtDNA to their children. 
This analysis requires an unbroken, all female chain of ancestors.  An identical match indicates that it is likely there is a shared female ancestor.  HVR1 analysis uses 54 sequences, HVR2 analysis uses another 51 sequences.

John Dolan-Heitlinger Information

Oldest Known Direct Male Ancestor:
Solomon Heitlinger -- John D-H's great grandfather, probably born between 1830 and 1857, German speaking, Jewish, lived in Vratimov, near Ostrava, in the modern Czech Republic.  He was likely from Silesia, Galicia, Poland or Hungary in Central Europe

His father may have been Aaron Heitlinger probably born in southern Poland before 1830. 

Oldest Known Direct Female Ancestor:
Anne Williams -- John D-H's 6th great grandmother, born probably in England before 1720 and likely emigrated to St. Mary's City Maryland which was first settled in 1634. 

Her daughter was Jane Pearce born between 1726 - 1745 probably in the largely Catholic, English settled community of St. Mary's, Maryland. She married John Layton, Sr. and they became part of the migration west first to northern Kentucky and then on to St. Genevieve, later Perry County, Missouri.

Data:
As of 16 June 2007 I had one exact match on the 12 marker test with and individual reported as Arab from Syria.  There have been no reports of close matches to my Y-DNA data on the 25 marker test. 

My Y-DNA haplogroup is E3b1c1 (old E3b3a).  This haplogroup is believed to have evolved in the Middle East. It expanded into the Mediterranean during the Pleistocene Neolithic expansion. It is currently distributed around the Mediterranean, southern Europe, and in north and east Africa

Since my male line is Jewish from central Europe this would fit into the theory that some central European Jewish communities were descended from the Jews exiled from Spain to northern Europe following the Reconquista by Los Reyes Católicos, Isabel y Fernando in 1492.

Data:
HVR1 Haplogroup H* (Helena)
Helena's descendants are the most numerous in Europe, having started 20,000 years ago from a hunting family in the Dordogne region of southwest France. After the Ice Age her clan moved north, reaching Britain about 12,000 years ago.

HVR1 Mutations 16519C
HVR2 Mutations 263G, 309.1C, 309.2C, 315.1C 

The Family Tree DNA database high resolution HVR2 matches have lines that go back to English, Irish, and Scandinavian ancestors.
