Thomas Greve is a genealogical researcher and speaker from Cape Cod, Massachusetts. After pursuing the history of his own family for over 10 years, Thomas began researching professionally in 2016. He holds a Certificate in Genealogical Research from Boston University, and currently serves as president of Falmouth Genealogical Society. He is also a proud member of Unclaimed Persons, a group of volunteer genealogists who donate their time and research skills to assist medical examiners, coroners and investigators to locate the next-of-kin of deceased individuals whose relatives have proven difficult to trace.

Thomas specializes in the use of DNA testing as evidence of identity and kinship, and enjoys helping adoptees and foundlings locate biological family members. Local research specialties include the Massachusetts counties of Barnstable, Bristol, and Worcester.
