(Analysis comparing the Big-Y Matches of Marshall Lake to David Lake (who has a paper trail back to the Gravesend LAKEs).) Date: Sun, 12 Apr 2020 01:38:18 -0400 From: Craig Kanalley BEGIN On Big Y, thanks for sending the screenshots.  I wanted to show a way you can determine which variants/SNPs might be unique to Marshall, which ones to David & which ones to some of our top Big Y matches by comparing the screens. Let's look at Marshall first.  I'm just looking at Marshall to David, and Marshall's next top 3 Big Y matches, Charles E. Bryan, Gerald C. Eastlick, and Brent Whear. MarshallBig-YMatches.png SNPs/variants boxed in YELLOW were determined to be UNIQUE to Marshall - he differs from David *and* others listed on these variants. And now let's look at David: DavidBig-YMatches.png SNPs/variants in ORANGE are UNIQUE to David - he differs from Marshall *and* others listed on these variants. For both screenshots - Charles E. Bryan has RED boxed variants/SNPs Gerald C. Eastlick has BLUE boxed variants/SNPs Brent Whear has GREEN boxed variants/SNPs These Red, Blue & Green variants/SNPs are variants that both Lake kits (Marshall & David) are NOT matching.  That is, they are either unique in the Bryan, Eastlick or Whear lines since our common ancestor, OR they are unique in our Lake line since the common ancestor.  In each case, our Lake kits tested POSITIVE and the other kits tested NEGATIVE, *or* the others tested POSITIVE and the Lake kits tested NEGATIVE- that is why they aren't matching. The "Block Tree" - on the other screenshot - focused on what variants ARE shared, but these are the variants that are not shared. Going back to the uniqueness of the Lake lines, and where they branch off - I count 8 yellow circled variants/SNPs that are unique to Marshall.  These are differences which would have arisen after the common ancestor of John Lake b. abt 1654 Gravesend because he does not match David on these markers.  So they indicate mutations for Thomas Lake b.abt 1680, Thomas Lake b.1718 or other Lakes later down the line to Marshall. For David, I count 7 orange circled variants/SNPs.  These are differences that would have arisen after the common ancestor of John Lake b. abt 1654 Gravesend, because he does not match Marshall on these markers.  So a mutation for Nicholas Lake b.abt 1692, John Lake b.1728 or Lakes later down the line to David. Likewise, once again, the Red, Blue & Green are variants born to the unique Bryan, Eastlick or Whear lines *OR* where our Lake line had a mutation & differentiates, after the common ancestor. Based on this analysis, the Eastlick appears to be our closest match, and this is supported by Y-111 which has Gerald C. Eastlick 8 steps from David Lake, the same distance as Marshall, and a David T. Eastlick 7 steps out from David Lake at Y-111 who did not do the Big Y.  This is also supported by the Big Y Block Tree which places Gerald C. Eastlick in our Lake block R-A14182.  There is an average of 8 private variants between these men, including David and Marshall.  The Eastlick/Eastlake and Lake intersection is one we need to study further, and I agree about reaching out to Brent Whear to compare notes with him. The only caveat on the above, where I boxed variants - sometimes there is a "NO CALL" or a "?" for a variant/SNP.  It is rare, but it happens.  These may *appear* non-shared, but in reality, they may be shared.  Each marker can individually be looked up in FTDNA in the Big Y tools provided, so you can see if you had a + or - read, or a ? (NO CALL). All in all, it is exciting to have proof that our John Lake b.abt.1654 Gravesend belonged to this R-A14182 haplogroup. These is a genealogical relationship with these Eastlicks/Eastlakes. Southwest England has come into focus, Cornwall and Devon.  As Wesley noted, if it is Cornwall, there are records that pre-date our Lake's immigration.  And I know we had an interesting thread earlier about a Sir Francis Leake of North Yorkshire, but geographically and genealogically, unless there was a major move, that doesn't seem to be where the DNA evidence is pointing.
