Group A1

Members generally have matches at 111 markers with genetic distances varying up to 10 steps.  This would seem to indicate a set of results for one branch of the name.

The members who have tested for Y700 converge on the most recent common male ancestor R-BY3537 sometime in the first millennium CE - see the Group Time Tree.

The family of Michael McCarthy have an opinion from a case study by Mr. Tyrone Bowes of 'Origenes' that their family is descended from the Noonans, which would seem correct.

A possible ancestral location for this group is the area of South Eastern County Limerick.

Group A2

Members have the exact 12 markers as Group A1.  They have not tested beyond 12 markers.

There are/were other Noonan exact 12 marker matches in the ftdna database.  They have either left or not joined this project. 

The Most Distant Known Ancestor for kit N79324 was George Noonan of Scotland (previously Ireland ?).

Group B1

Members have a match at 37 markers with a genetic distance of 3 steps.

There is 1 other Noonan 37 marker match with a genetic distance of 4 steps in the ftdna database.  They have not joined this project.

Group B2

Member has 11 (of 12) markers of one member from group B1.

Group C1

Member 956441 has historic ties to the region around Carrignavar, County Cork and this group has been created to cater for future matches.

Group D1

Members have tested for Y700 and converge on the most recent common male ancestor R-DF85 sometime about 300 CE- see the Group Time Tree.

Group T

Kit 267204 presents with the unusual Y-DNA haplogroup T.  A second cousin of this member (not in this group) was tested and is also haplogroup T.

The member believes this match confirms their common male ancestor George Noonan born c1800 was also haplogroup T.

Others

Other members don't have any matches yet.
