Learn English – single word which means “a person, and all of his ancestors”, or “a person, and all of his descendants”

collective-nounsnounssingle-word-requeststerminology

There are a lot of words describing ancestral relationships between people, such as:

parent
grandparent
great-grandparent
any of the above can be described as an "ancestor".

child
grandchild
great-grandchild
any of the above can be described as a "descendant".

I am wondering if there are single words (nouns) which describe any of the following concepts:

A person and all of his/her ancestors
A person or any of his/her ancestors
A person and all of his/her descendants
A person or any of his/her descendants

Any ideas?

Lineage comes to mind (as did Line but I prefer lineage)

  1. lineal descent from an ancestor; ancestry or extraction: She could trace her lineage to the early Pilgrims.
  2. the line of descendants of a particular ancestor; family; race.

Since there is some discussion about whether or not the person itself belongs to the lineage, I offer this ngram of "last of his lineage"
