When you're stuck on a direct ancestor, researching their siblings and cousins (collateral lines) can reveal crucial details about the whole family—where they moved, who they married, when they arrived—that apply directly to your brick wall ancestor. This sidesteps the wall by working around it.
The collateral line strategy involves researching the siblings, cousins, and extended relatives of a brick wall ancestor rather than the ancestor directly, because records about nearby family members often contain indirect clues about the target individual. This approach is especially useful when direct records for an ancestor have been lost, destroyed, or never existed.
AI accelerates this process by scanning multiple family branches simultaneously, identifying record overlaps across collateral lines, and flagging shared witnesses, neighbors, or godparents who may link back to the missing ancestor and unlock previously hidden documentation.
