Identify a direct maternal line descendant of Kesiah and have him or her take the mtDNAPlus test from Family Tree DNA. The tester's mother's mother's mother's etc. mother would need to be Kesiah. If the mtDNA results come back as haplogroup A, B, C, D, or some types of X then it is likely Native American. Hopefully it is you who fits the criteria as the direct maternal line descendant. Otherwise, you can then use autosomal and X-DNA testing of descendants of Kesiah to try to confirm the parent / child relationships from you back to Kesiah.
