About Carol

Carol Isbister Rolnick is a Genetic Genealogy consultant and leading researcher in the genetic genealogy community, specializing in the use of DNA to identify unknown family.  Carol has helped scores of adoptees and others of unknown parentage to find their biological family, including the widely publicized case of Paul Fronczak, who published his story in a highly acclaimed book “The Foundling.” 


Carol specializes in autosomal DNA research to solve unknown paternity, adoption, foundlings, and recent unknown ancestry, but is proficient in the use of both y-DNA and mt-DNA as well.  She also has a keen interest in the overlap of medical genetics with genealogy, managing projects for rare inherited diseases to identify family who are potential carriers to reduce risk and expedite treatment and support.


Bitten by the genealogy bug from an early age, she discovered an even greater passion for genetic genealogy beginning in the very early days of testing.  The field satisfies her love of science, big data and an insatiable desire to help others solve personal mysteries.


She is a member of the International Society of Genetic Genealogists, the North San Diego County Genealogical Society, the Association of Professional Genealogists and the National Genealogical Society.
