As the president of Texas-based FHD Forensics, Allison Peacock turned a passionate 20 year hobby into a new career as a genealogical detective in 2018 after 35 years in corporate consulting. She and her team perform unknown subject identifications using investigative genetic genealogy (IGG) in collaboration with law enforcement, archaeologists, and trafficking survivors.

In 2023, she served as expert witness in a Common Law precedent-setting case in Canada using IGG to establish paternity for the endangered child of an international sex worker. She currently manages a project for FHD’s sister organization Genealogy For Justice assisting families that survived the Georgia Tann baby selling ring that operated with impunity in the state of Tennessee from 1924-1950.

Some of her favorite DNA identification projects include solving the paternity of a man born in South Carolina in 1856, confirmation of a client’s relationship to explorer Daniel Boone, the identity of an international black market adoption survivor, a dual perpetrator Midwestern homicide case, and assisting the families of two Texas murder victims with locating the couple’s missing daughter after 41 years. That 2021 case led to the innovative creation of the Dean and Tina Linn Clouse Memorial Fund to underwrite unidentified remains cases, providing the opportunity for their families to turn their pain into purpose. She now serves as the Advisory Board Chairman for Genealogy For Justice, the nonprofit dedicated to managing this fund and addressing the cold crisis through crowdfunding and philanthropy.

Her most recent undertaking is the study of some of the world’s oldest autosomal DNA profiles for the Camden Fourteen DNA Project. These are the unknown subject identifications of Revolutionary War casualties from the Battle of Camden that took place August 16, 1780 in South Carolina. She calls this work to learn more about America’s first veterans “the investigation of a lifetime.” Peacock and her team announced the first unknown soldier’s identity in June 2026. A unique next of kin notification for 100 people introduced Private John Pumphrey, a teen from Maryland’s 7th Regiment, to the world in the shadow of his boyhood home at the historic Benson-Hammond House in Maryland. A second identification is forthcoming.

An avid storyteller, Peacock has authored memoirs and family history books for private clients. She also created and hosted the Family History Detectives® podcast in 2023 to share Clouse-Linn family interviews. Her collaboration with journalist Cristina Corbin entitled What About Holly? was a Top Five true crime title on Apple Podcasts. Allison has been interviewed on the subject of genetic genealogy by various news outlets and most every major American media network, such as NPR: All Things Considered GMA3, Washington Post, CBS Saturday Morning, USA Today, CNN Tonight; as well as television shows ABC 20/20, PBS’ Secrets of the Dead (in production), and Bloodline Detectives. 

A devoted mother and grandmother, as well as a life-long flower gardener, Allison is now a proud Upstate New York resident.
