I have developed a technique that can detect Sephardic ancestry in persons who are ostensibly Ashkenazic. For persons who have already done the basic genetic genealogy test (such as Family Finder, 23andMe, AncestryDNA), no further testing is necessary. A file conversion is necessary which is not expensive, and the modeling chart is even less than that (together US$20). To view a sample study: https://1drv.ms/u/s!AuwT-4qnkJLBjk1EnhIe9qQb_Uq2?e=jyY1Dd If your result is in the shaded area, then Sephardic ancestry is confirmed. For more information contact me privately.
