Our DNA: We are Sheets Lineage 2 http://worldfamilies.net/surnames/s/sheets/results.html
We do not have DNA samples from Jacob!
We do have DNA evidence that our testors from different branches are related to a common ancestor. The names and the family trees come from us, historians and genealogists. This means that when we match with different branches of Jacob (5 matches so far), we can combine our knowledge and known histories of these ancestors. One day, one of the branches may find information that we don't have.
There eventually could be a common line discovered but evidence points to more likely a brother of Jacob. Maybe Mathias or Yost are that brother. We do not know for sure yet but our earliest family genealogists knew of these possible brothers as well.
This is our DNA Haplogroup. R1b1b2 from which scientists are tracking DNA of ancient ancestors all over the world. Our ancestors were one of the first migrating groups from Africa into Europe.
Its frequency is highest in Western Europe, especially in Atlantic Europe (and due to European emigration, in North America, South America, and Australia). In southern England, the frequency of R1b is about 70%, and in parts of north and western England, Spain, Portugal, France, Wales, Scotland and Ireland, the frequency of R1b is greater than 90%.[citation needed] It is also found in North Africa where its frequency surpasses 10% in some parts of Algeria[2].
R1b is also current in many different populations at Ural and Central Asia.
Haplogroup R1b is defined by the presence of single nucleotide polymorphism (SNP) M343, which was discovered in 2004.[3] From 2002 to 2005, R1b was defined by the presence of SNP P25; prior to 2002, today's Haplogroup R1b had a number of names in differing nomenclature systems, such as Hg1 and Eu18.[4]
