There are many untested submissions that are match the L744 fingerprint that could be tested. For over 70 % matches to the L744 fingerprint, only 18 of 84 submissions have been tested to date. This analysis includes submissions from the L21 Plus spreadsheet, the Stewart project and a L744 Y-Search query.

1) For submissions with over 80 % matches, only 17 of 76 testing candidates have been tested positive to date. However, it is not necessary to test the majority of these testing candidates. Only those with non-Stewart surnames that have not been tested to date are the best testing candidates. If any Stewart submission has not been tested and none of his genealogical cousins have not been tested to date, then these submissions could continue to test for L744 as well. Above 80 % matches, the majority are submissions have the surname of Stewart or a Stewart variant (56 out of 76). All Stewart submissions above 80 % matches have tested positive to date (12 of 12). The following non-Stewart submissions are the best testing candidates: Bowlin (85883), Campbell (129498), FitzAlan (AHEPZ) and Sands (G9EYY).

2) For submissions between 70 % and 80 % matches (7 of 9 match), only non-Stewart surname submissions are found. It is highly recommended that all submissions in this group continue testing (unless genealogically related to tested submission). The following submissions would be very good testing candidates: Abdrew (171684), Brown (92148), Coffey (175650), Harris (213153), Hughson (15651), Wall (AMXSW) and Winn (81480). These submissions are best testing candidates to determine the boundary conditions of the L744 related SNPs which best advances L744 research.

3) There are around 85 additional testing candidates that match between 60 and 70 % of the L744 fingerprint (6 of 9 match). Even though the vast majority of these submissions will test negative for L744, a handful of these testing candidates should test positive. The submissions with the lowest genetic distance from the L744 fingerprint make the best testing candidates. Testing of submissions between 60 and 70 % should be considered speculative in nature but would be signficant discoveries if found positive. Based on the lowest genetic distance from the L744 fingerprint, the top ten testing candidates include: Anderson (124121), Gutierrez (4W7SB), Haley (N6Q3R), Healy (53716), Humphries (UCTSJ), Mahony (184162), McCartney (202776), Moore (79882), Muller (113882) and Polk (VEWVM).

4) There are a staggering 282 submissons that match between 50 and 60 % of the L744 fingerprint. However, there are several testing candidates with lower genetic distance that warrant testing. Based on the lowest genetic distance from the L744 fingerprint, the top five testing candidates include: Donahue (12294), Flynn (H95P9), Franklin (54798), Lewis (122927) and McCarthy (145487).

The DNA results spreadsheet includes the following good testing candidates:

9 of 9 match - non-Stewart surnames = 2 (Stewart submissions under some conditions)
8 of 9 match - non-Stewart surnames = 2 (Stewart submissions under some conditions)
7 of 9 match - all submissions = 7 (best testing candidates for L744 research)
6 of 9 match - top ten with least genetic distance = 10 (somewhat speculative)
5 of 9 match - top five with least genetic distance = 5 (somewhat speculative)
4 of 9 match or lower - not recommended for any match under 50 %
