The I-FT11343 haplogroup has a common ancestor who lived approximately 1,000 years ago, and very likely he was named Lindsay. All I-FT11343 men are named Lindsay/Lindsey/Lindesay or similar, or are very likely paternally descended from Lindsay men.
This update shows a new branch called I-BY189035, it's part of I-FT97878. On our previous trees, BY189035 and FT97878 were considered to be equivalent. There are now four I-FT97878 samples, two of them belong to the more specific I-BY189035 haplogroup. All 4 men are American and their Lindsay ancestors have been in the USA since the 1700s, maybe they are all descended from the same immigrant Lindsay ancestor. YFull estimates that their common ancestor lived 400 years ago.
If you look at our tree, you will see that the I-FT97878 and I-BY189035 branches are a small, specific and recent part of I-FT11343. The Lindsay family is large and it has been expanding continuously for approximately 1000 years.
This update also shows some new SNP information for other branches, indicated in red

There are some important differences between our draft tree/FTDNA's tree and the YFull tree. This is because the YFull tree doesn't contain all the Big Y samples from FTDNA. And some of the samples at YFull are from Big Y-500 tests, in some cases men have completed an update to Big Y-700 but they haven't sent their new BAM file to YFull.
The YFull tree shows a branch called I-Y36039, and YFull shows Y36039, FT113343, A16520, A16521, A16524, Y168200, FGC48786/YP5849 as equivalent SNPs.
In fact A16520, A16521, A16524, Y168200, FGC48786/YP5849 are equivalent (and some new FT series SNPs are also equivalent), but I-Y36039 is a more specific haplogroup, and I-FT113343 is an even more specific haplogroup. You can see these details on our project's I-A8462 tree and on FTDNA's I-A8462 tree, click here for our latest post about I-A8462
When you compare the trees, this I-FT11343 draft tree and FTDNA's I-FT11343 haplotree/Big Y Block tree contain YFull's I-Y138968 branch and YFull's large I-F25958 branch. But YFull's I-Y36040 branch is in fact FT11343- (and I-Y36040 contains no Lindsay men). Eventually people will send new BAM and VCF files to YFull, and YFull will update its tree.
