Before 1850, U.S. census records listed household members using tick marks rather than names. During this program, Linda Debe will demonstrate how to identify individuals hidden behind the tick marks used in U.S. census records from 1790–1840. Learn how to collect and analyze census data using an automated Excel spreadsheet, compare findings with later census records, assign names to household members, reconstruct family groups, and verify your conclusions. Participants will receive a ready-to-use Excel tool designed to help uncover missing details and bridge gaps in their family history research.
Presented by Linda Debe.
