I-S21825 contains some of the least common branches in I-P37. All known modern men in I-S21825 belong to one of four branches:

• I-L1294 "France", this is the group with DYS388=9. Almost all known samples at FTDNA have British/Irish origin, but this group may be more common in France and Spain. 
• I-M838 also known as I-L880 "Northern France" this is a poorly known group with a MRCA who lived 6400 years ago according to YFull's estimate. There are only two Big Y/NGS samples of modern men for this group, both are Big Y-500 samples
• I-L233 "Western" which has a MRCA who lived 2100 years ago. There are 193 Big Y samples for I-L233
• I-A8689 "Alpine" also known as I-Y11949, which has a MRCA who lived 2900 years ago. This group is closely related to I-L233

This I-S21825 tree shows details about all of these branches except I-L233, which has several trees of its own.

This update shows a new branch in I-L1294 thanks to a new Big Y-700 sample. There are now 2 Big Y-700 samples and 5 Big Y-500 samples for I-L1294.

There are now 3 Big Y-700 samples and 1 Big Y-500 sample in I-A8689 "Alpine". One of the Big Y-700 tests was completed in December 2020, he has origin from Turkey according to FTDNA's trees. But he isn't a member of the I-P37 project and we have no way to communicate with him. His result didn't add a new branch to the tree, he belongs to an unnamed I-A8689* branch.

As mentioned, I-M838 contains only two modern samples, one with origin in northwestern France and one with origin in Rheinland-Pfalz in Western Germany. But FTDNA and YFull show an ancient DNA I-M838 sample. This is ERS3968402, from a Wartburg culture collective burial also in Rheinland-Pfalz (approximately 5200 years old). See https://www.biorxiv.org/content/10.1101/851188v1  The common ancestor of ERS3968402 and the German Big Y-500 sample lived approximately 5700 years ago, they form the new I-BY73844 branch. We will try to organize Big Y-700 tests for more members of I-M838.

This update also shows major new branches named I-FT344596 and I-FT344600. These are based on ancient DNA samples from Ireland and Sweden as shown on the YFull and FTDNA trees. See https://www.yfull.com/samples-from-paper/443/ and https://www.yfull.com/samples-from-paper/388/ 

There are several additional ancient DNA samples/branches that are shown on FTDNA and YFull's tree, see links below
