Here's a breakdown of what you might be referring to:
* Patrilineal descent: Tracing your lineage through your father, grandfather, great-grandfather, etc.
* Matrilineal descent: Tracing your lineage through your mother, grandmother, great-grandmother, etc.
* Bilineal descent: Tracing your lineage through both your mother and father's sides.
* Collateral lineage: Tracing your lineage through siblings, aunts, uncles, cousins, etc.
To further clarify your question, it would be helpful to know:
* Which side of the family are you interested in? (e.g., mother's side, father's side, specific ancestor)
* What specific ancestor are you trying to trace?
* What are your goals for tracing this lineage? (e.g., finding out about family history, connecting with distant relatives, etc.)
Once you provide more information, I can give you more specific guidance on how to trace your ancestry through that branch of your family.
