About this webinar

How do we critically assess both the evidence we have—and the gaps where records are missing? How can one document point the way to another, and how do we strengthen our hunches and hypotheses with DNA analysis? In this case study, we will search for the parentage of Eliza Ann Sample Keister (1827-1876) through a wide range of records. Join the journey, test your own analytical skills, and see if you can spot the “next step” that just might topple the brick wall.

Key points and insights

Breaking through stubborn genealogical brick walls demands moving beyond direct records into rigorous, strategic problem solving. In this dynamic case study presented by Dr. Michael D. Lacopo for Legacy Family Tree Webinars, researchers are taken on an investigative journey to identify the elusive parents of nineteenth-century ancestor Eliza Ann Sample. Facing a complete absence of direct birth, marriage, or death records, the presentation demonstrates how adhering strictly to the Genealogical Proof Standard can turn an apparent dead end into a compelling genealogical success story.

  • Strategic Exclusion Rules Candidates In: When direct documentation is missing, assembling a broad candidate pool and systematically disproving possibilities is just as crucial as finding positive evidence. By rigorously comparing census tick marks, estate files, and land records, potential fathers such as Hugh and Andrew Sample were methodically eliminated, narrowing focus to the one family that truly fit the evidence.
  • Local Nuance and Negative Space Yield Fresh Clues: Overcoming historical dead ends requires an understanding of regional legal terminology, historical boundary shifts, and unconventional archives. Untangling records across shifting county borders and examining underutilized sources—such as Pennsylvania inmate tax entries, poor school children registers, and local Presbyterian session minutes—uncovered critical footprints left behind by tenant-farming ancestors who owned no land.
  • Genetic Genealogy Bolsters Rather Than Replaces Traditional Proof: Modern DNA analysis serves as a powerful instrument to substantiate an existing documentary argument rather than acting as a shortcut. While misattributed online family trees lacked paper trails to signal ancestral relationships, multi-generational autosomal DNA match clusters provided the final verification needed to confirm the circumstantial hypothesis.

To experience how these intricate methodologies unfold step by step and to observe the exact records, timelines, and proof arguments in action, watching the full recorded session is essential viewing for anyone tackling tough lineage obstacles. Genealogists looking to sharpen their analytical skills will gain tremendous value from exploring the comprehensive supplementary materials included in the syllabus, packed with helpful guides and research strategies designed to empower future ancestral discoveries.

    Great webinar. Excellent advice on ruling people in/out, looking for records no one else is using, and reconstructing extended families to find (or not find) connections.

    This was really fun. He makes it sound so real. It gives me encouragement to read and re-read every census where my family is listed. Thank you. Clara Lawver in NE

    Wow! Amazing case study and presentation! (I would have listened all day long!) This was probably the most similar case study I have ever seen that relates directly to my huge brick wall. Seeing the realistic "dead ends" and how to redirect research to other avenues was extremely valuable to me. Thank you for the great ideas!

    Wonderful example of the depths of "exhaustive" research you sometimes to go to to try and solve that impenetrable brick wall. I have one of those that is giving me fits and there are suggestions in the webinar on things to try. Thank You and Well Done!
