Abstract: A presentation of research which examined the genetic origins and postsettlement gene flow of Chamorros of the Marianas Islands. The procedure was to infer the origins of the Chamorros by analyzing 360 base pairs of the hypervariable-region 1 (HVS1) of mitochondrial DNA from 105 Chamorros and compared them to lineages from ISEA and neighboring Pacific archipelagoes from the database. As a result, 92% of Chamorros belong to haplogroup E, also found in ISEA but rare in Oceania. The two most numerous E lineages were identical to lineages currently found in Indonesia, while the remaining E lineages differed by only one or two mutations and all were unique to the Marianas. Editor’s Note: This paper, presented at the Marianas History Conference, was not made available for publication.
