Genealogical researcher specializing in the Northeastern United States and Quebec, Canada, with expertise in regional records, cross-border ancestry, and complex research problems, including brick wall cases. My work focuses on building accurate, evidence-based family histories through thorough analysis of historical records and contextual sources.

I have particular experience in DNA analysis and unknown parentage cases, utilizing autosomal DNA, cluster research, WATO, and chromosome triangulation to resolve challenging lineage questions. My research approach also includes archival and on-site work, drawing from courthouses, libraries, and historical societies to access records not available online.

My specialties include Colonial and early American research, immigration and migration studies—especially French-Canadian movement into New England—and U.S. military records from the Revolutionary War through World War II. I am also experienced in international research through digital archives, including Quebec notarial records, English parish registers, and Bohemian church records.

I regularly conduct research in New England, New York, and Quebec, with additional experience in Illinois, New Brunswick, and online archival research in England and the Czech Republic.

I am committed to ongoing professional development through programs such as Board for Certification of Genealogists educational offerings and industry-leading institutes, and I am currently a certification applicant with the Board for Certification of Genealogists.
