A Croatian branch of I-A10033: 2018-12-24 tree for I-L233

Click here to download our 2018-12-24 tree for I-L233

Beginning with this update, we have moved our I-A8462 information to a new tree, click here to find it. At this point, all known I-A8462 members have paternal ancestry from Great Britain.

The other members of I-L233 belong to the I-Y4252 branch which is found in Great Britain and in continental Europe. I-Y4252 rapidly expanded into 11 named branches and 8 unnamed branches, as shown on this tree, and probably we will find more branches. All of these branches have been found in Great Britain, which is partly a reflection of the origin of most FTDNA customers.

Only one branch, I-A10033, is largely continental European. One branch of I-A10033 is called I-A10034, and it contains men with ancestry from Denmark, Schleswig-Holstein (Germany), northwestern Germany and the Netherlands. I-A10034 only contains one known man with British origin, he is from Northeastern England which was an area settled by Danes more than 1000 years ago, and he has a family tradition of ancient Danish origin.

This tree shows a second branch of I-A10033, it's called I-Y60701. The two known members have paternal ancestry from modern Croatia: one from the Istria peninsula and one from the hinterland of Dalmatia. They aren't close relatives, based on the number of private variants found in each man, their common ancestor probably lived more than 500 years ago. They aren't close STR matches, they are a Genetic Distance=21 when Y111 markers are compared. One of these Big Ys was funded by the members of the I-P37 project at FTDNA.
******************
This update also shows new branches/SNP information for three families (Auld, Terry, Hawkins). Each of these families are represented by at least 3 Big Y results.
