Park Street Research, LLC
Park Street Research
is a partnership
of two professional
Genealogists with over 45 years of combined research experience.
We do all of our own research and share a passion for using Genealogy Research as a Forensic Tool
to assist Coroners & Medical Examiners.
Park Street Research identifies and locates surviving Next-of-Kin for Coroner and Medical Examiner cases where the name of the deceased is known, but the identity of the Next-of-Kin is unknown. We do not contact family members, friends or employers of the deceased.
We work all cases using a team approach, perform 100% of all research in-house, and co-write all NOK Case Summary Reports.
Park Street Research, LLC, limits all casework to requests from Coroners, Medical Examiners and other Law Enforcement agencies.
We do not accept requests for Family Tree or routine genealogy projects.
