My eldest son moved up a reading level at school today.
He was the second child and the eldest son of the couple.
He is the third of five children, and the eldest son.
They are passed on from the father to the eldest son.
Only to an eldest son could I open my heart.
He was the second child of four and their eldest son.
He is the eldest son in a family of two.
His eldest son was beginning to take interest in my words.
I haven't seen my eldest son in two or maybe three weeks.
His father had wanted him, the eldest son, to take over the family business.
