Organized family tree summary of what's known (pedigree chart format)\n2. Identified gaps ranked by resolvability\n3. Specific record types to search for each gap (census, vital records, ship manifests, church records)\n4. Search strategies for each database I listed\n5. Name variant list for spelling searches (critical for immigrant surnames)\n6. Timeline of likely migration/life events to guide document dating

Tips for Better Results
Paste every name spelling you've ever seen for each ancestor — immigrant names were phonetically anglicized in different ways by different clerks, and searching all variants is essential.
