With a long track record of successfully completing due diligence and kinship cases and locating missing and unknown heirs, we are certified genealogists offering skilled repository and online research. We work with a network of genealogists and investigators throughout the United States and overseas to follow the research trail where it leads.

Familiar with the burden of proof demanded by the courts, we assemble documents, prepare family tree charts, write affidavits, and provide expert witness testimony.

Whether you need to locate one heir or trace four generations of a decedent’s paternal and maternal lines, we have the expertise, resources, and determination to obtain results quickly, reliably, and cost-effectively.

Certified & Forensic Genealogists

Leslie Corn, CG, MA, FGBS

A fifth-generation Manhattan native, Leslie Corn has been intrigued with her hometown, its history and families, since she was a child. She’s a former award-winning programmer, producer, and writer with CBS, ABC, and her own production company. One day, while on break from jury duty in downtown Manhattan, Leslie wandered into the New York City Municipal Archives. It was instant fascination and a gradual change of profession. She began her training by volunteering at the New York County Clerk’s Office/ Division of Old Records. With its wealth of documents, brilliant and generous archivists, and archival dust, it remains her favorite New York City repository. For the past 24 years, she’s worked with attorneys, executors, administrators, attorneys for Public Administrators, realtors, banks, investigators, heir searchers, museums, and private clients in the search for people who need to be found, living or deceased. She is an author, workshop leader, and speaker about repository and online research, at local and national conferences and on-air, including on the genealogical documentary series, Who Do You Think You Are?, where she served as genealogist during its NBC run. She currently contributes to the series on BBC-TV. A graduate of the National Institute on Genealogical Research at the National Archives in Washington, D.C., she also holds a B.A. in English and M.A. in Psychology. She authored The Guide to New York City Research for the New England Historic Genealogical Society and ProQuest Information and Learning Corporation’s Quick-Start Guide for Genealogists about their Historical Newspaper CollectionTM. In 2003, Leslie was named the 61st Fellow of The New York Genealogical and Biographical Society (FGBS). She is qualified as an expert witness in New York Surrogate’s Courts.
