This page has recommendations for using WikiTree in genetic genealogy before the Confirmed with DNA status indicator can be used on individual parent-child relationships. See DNA Features for an overview of WikiTree's genetic genealogy tools.

Y-DNA Test Connections Where the Shared Direct Paternal Line Ancestor is Unknown

In surname DNA projects there are often males with the same surname who have matching Y-DNA but their shared patriarch has not yet been found. These males can be categorized into unique groups by adding a code such as [[Category:Roberts Y-STR Group 1]] at the top of the profile of the tester's earliest known direct paternal ancestor. Simply replace Roberts with the surname for your cluster and be sure each surname group has a different number.

To see the descendant(s) who was Y-DNA tested, click on the ancestor (e.g. at Roberts Y-STR Group 1 ) and he is displayed, in the upper right of his profile, under Y-chromosome DNA test-takers.

To see all the Y chromosome descendants of each of these ancestors, click on the ancestor (e.g. at Roberts Y-STR Group 1 ) and then on the upper right of his profile, under DNA Connections, click on the link for carriers of his Y-chromosome.

To independently verify this group sufficiently matches, go to YSearch to compare the YSearch IDs of the descendants who were Y-DNA tested. If they match about 90% of their markers or closer, and they share similar surnames, then they most likely share a direct paternal line ancestor with that surname in a genealogical time frame.

In order to insure independent verification, it is required that each Y-DNA tester's YSearch ID be on their DNA Tests page in WikiTree, or that a link is provided to the tester's Y-STR haplotype in a publicly accessible file, chart, or table, etc. It is also required that the tester's direct paternal ancestral line be in WikiTree.

Mitochondrial Test Connections Where the Shared Direct Maternal Line Ancestry is Unknown

In geographic DNA projects there are often persons in the same mtDNA haplogroup who match on HVR1 and HVR2 but their shared matriarch has not yet been found. These people can be categorized into unique groups by adding a code such as [[Category:H6a1a mtDNA Group 2]] at the top of the profile of the tester's earliest known direct maternal ancestor. Simply replace H6a1a with the haplogroup for your cluster and be sure each mtDNA group has a different number.

To see the descendant(s) who was mtDNA tested, click on the ancestor (e.g. at H6a1a mtDNA Group 2 ) and they are displayed under Mitochondrial DNA test-takers.

To see all the mitochondrial DNA descendants of each of these ancestors, click on the ancestor (e.g. at H6a1a mtDNA Group 2 ) and then on the upper right of her profile, under DNA Connections, click on the link for "carriers of her mitochondrial DNA."

To independently verify this group matches on HVR1 and HVR2 go to MitoSearch to compare the MitoSearch IDs of the descendants who were mtDNA tested. If they exactly match or only have a minor mismatch and they trace back to the same geographical area then they likely share a direct maternal line ancestor who lived in that geographic area in a genealogical time frame.

In order to insure independent verification, it is required that each mtDNA tester's MitoSearch ID be on their DNA Tests page in WikiTree, or that a link is provided to the tester's mtDNA differences from the rCRS which are in a publicly accessible file, chart, or table, etc. It is also required that the tester's direct maternal ancestral line be in WikiTree.

Autosomal Matches Where the Shared Ancestry is Unknown

It's common for Family Tree DNA Family Finder, 23andMe, and AncestryDNA to report matches with a certain level of confidence. You can conclude that there is shared ancestry in a genealogical time frame but you can't mark individual parent-child relationships as Confirmed with DNA using the standards described in the Acceptable Confirmation Methods section.

Categorization could probably be used for this, but how? We need someone to think this through and experiment. Please help!
