I've changed the estimated birth to an earlier year with cause related to Margaret Douglas, Countess of Atholl 's death date. I doubt the mother's three daughters were spaced out from 1561 to 1473. For Margaret Douglas, Countess of Atholl to have given birth after age 40 becomes increasingly implausible.
From extant records, the birth order for Christen and sisters appears as follows, and I suggest changing Elizabeth's birth as showing below.
— Janet ‘Jean’ Stewart, Countess of Huntly b. circa 1561
— Elizabeth Stewart b. circa 1563
— Christian Stewart b. circa 1565
