I am a Forensic Lineage Specialist focused on the precise reconstruction of family histories across Ontario, Quebec, and the United Kingdom. My work blends documentary research, DNA analysis, and historical context to resolve complex identity questions, including Non‑Paternal Events (NPEs), misattributed parentage, and multi‑branch kinship puzzles.

With an academic background in Geography, I bring a unique lens to genealogical research—tracking migration routes, occupational movements, and the social landscapes that shaped families from London, the Midlands, Bristol, and the St. Lawrence Corridor. This geographic perspective allows me to interpret records not just as isolated facts, but as part of a lived environment.

I maintain advanced professional proficiency in French reading and writing, enabling me to translate and interpret Quebec parish records, notarial acts, and early colonial documents into clear, evidence‑based English reports.

My methodology integrates both traditional and modern tools, including:

• multi‑kit DNA management and cluster analysis
• 17th–19th century British and colonial record interpretation
• contextual historical research
• careful correlation of genetic and documentary evidence
• optional forensic techniques such as biometric photo comparison and uniform identification

Whether reconstructing a lost lineage, interpreting DNA matches, or writing a narrative ancestor profile, my goal is always the same: to bring clarity, dignity, and meaning to the stories families carry.
