The only surname currently testing positive for this L9 and L10 is one Gilroy submission. There are currently three R1b Gilroy submissions that belong to the Gilroy DNA Surname Project. Only one Gilroy has tested positive for both L9 and L10: FTDNA ID N56253 (Y-Search ID F9KZK). His oldest proven ancestor is shown as Edward Ralph Gilroy, b. 1852, St. Andrew, Jamaica, West Indies. The other two Gilroys have too low of fingerprint matches to be considered for L9 and L10 testing:

Good candidates for L9 & L10 testing (in order of relatedness):

1) For matches above 70 %, there are two excellent testing candidates. Goff, FTDNA 58526, Y-Search F9KZK, fingerprint match (67 markers) - 9 of 13 match and genetic distance of 8 and Vaughan, FTDNA 160729 - 9 of 13 match and genetic distance of 11. There is a second Goff submission, FTDNA 147436, however, both Goff submissions are exact 67 marker matches and are listed as descendants of John Goff, b. 1820, PA. After contacting the adminstrators for the Goff Surname project, the Goff submission 58526 has recently ordered L9 (not sure of L10 status).

2) There are eleven submissions that match between 60 and 70 % of the L9 fingerprint. Although somewhat speculative in nature, many of these submissions could test positive if L9 fingerprint is reduced in size. With only one positive submission to base the L9 fingerprint, these submissions have only a 10 to 20 % odds of testing positive. To see these submissions, download the L9&L10 spreadsheet via the DNA Results pull-down menu.

3) There are another thirty submissions that match between 50 and 60 % of the L9 fingerprint. Testing of these submissions is very speculative in nature but several could test positive if the L9 fingerprint requires refinement after more testing. With only one positive submission to base the L9 fingerprint, these submissions have only a 5 to 10 % odds of testing positive. To see these submissions, download the L9&L10 spreadsheet via the DNA Results pull-down menu.

Only test for those candidates that are highlighted in green, turquoise or yellow. The higher on the spreadsheet, the more likely of testing positive for L9 and L10. Since the scope of this L9 has not been well tested to date, these recommendations are less reliable in either direction. For any submission over 70 % matches, it is recommended that both L9 and L10 Y-SNPs be tested.
