Big Y Test

“The Big Y product is a direct paternal lineage test. We have designed it to explore deep ancestral links on our common paternal tree. It tests both thousands of known branch markers and millions of places where there may be new branch markers. We intend it for expert users with an interest in advancing science.” Family Tree DNA websitehttps://www.familytreedna.com/learn/y-dna-testing/big-y/

Your results include:

Known SNPs – Displays your single nucleotide polymorphisms (SNPs) that are on the list of ~36,000 known SNPs against which Big Y data is compared. From FTDNA https://www.familytreedna.com/learn/y-dna-testing/big-y-page/

Novel Varients - Displays your SNP markers that are not on the list of ~36,000 known SNPs. These markers may or may not be unique to you as an individual. Men in related lineages may share some novel variants. As men from distantly related lineages test, SNP markers may be moved from the Novel Variants to Known SNPs. From FTDNA https://www.familytreedna.com/learn/y-dna-testing/big-y-page/

Matching – Displays Big Y matches. A person is considered a match if they have four or less differences in SNPs with you (as opposed to marker differences). From FTDNA https://www.familytreedna.com/learn/y-dna-testing/big-y-page/

“Discovery of novel variants in samples will eventually assist refinement of the human evolutionary tree, thus improving our understanding of human genealogy.” From FTDNA From White Paper FTDNA https://www.familytreedna.com/learn/wp-content/uploads/2016/01/BIG_Y_WhitePager.pdf

Discovering more about surname origins

• A way to possibly pinpoint migrations

• My family has been curious about the ethnic origin of the names Forgey (was it Scottish or French origin?)

• Pinpoint, in time, more exactly when you share a common ancestor with matches

• Pinpoint when a surname was adopted (the Big Y test suggests Forgeys split with Ferguson around 300 years ago)

• Get available SNP’s (otherwise you have to buy them individually at a cost of $39 per SNP)

There are many SNP’s associated with our Haplogroup

Novel Variants Not On Haplotree (Not assigned a name yet)

Matches on Big Y based on SNP’s are somewhat different. This list include a Norwegian match not included on marker matches. Most matches are British Isles.

Filtering by Subclade

When filtering by our specific subclade all of our matches are Ferguson. This confirms the supposition that Forgey is a variant of Ferguson.

Hokstad is in a different haplogroup. Not sure why he is showing up as a 0 SNP difference and doesn’t share the same haplogroup?

More evaluation needs to be done to establish whether our ancient roots are Norwegian? We had thought I L126 had ancient Scottish roots.

Neither the marker test nor the Big Y test suggest French origins of the surname. The Scottish name Ferguson appears to be the root of the name.

A Diaz on the Big Y match list and a Hernandez on the 47 marker test are also puzzling?

Could be both Hokstad and the Spanish matches show up as matches because they are in the same upstream subclades such as the original haplogroups we were assigned to?

All shared Haplogroup matches are Ferguson

It is necessary to pay an extra $49 for the full Y which provides updated SNP and Haplogroup information and further personal analysis
