Baird was the eldest son of Sir William Baird who was the 2nd Baronet of the first baronetcy created for his father in 1660^[1] and 1st Baronet of the second baronetcy created for himself in 1680.^[2] His mother was Helen Gilmour, daughter of Sir John Gilmour.^[3] He was educated at the University of Glasgow in 1702 and was awarded MA in 1706. He married Janet Dalrymple, only daughter of Sir David Dalrymple, 1st Baronet of Hailes, Haddington.^[4]

Baird was returned unopposed as Member of Parliament (MP) for Edinburghshire at the 1715 general election. He was appointed Commissioner of the equivalent in 1715 and held the post until 1719.
