Do you mean kin-keeping? Old term for family is kinfolk, next of kin. Daughters generally step into the maternal role of taking care of family.

Older people do not very often support each other especially when one or all are reaching the point of needing physical and emotional support.

You siblings will trigger memories of mutual experiences.
