The Blair of Heslop & Blair was named David Blair and was probably the same David or the father of the later David (the Heslop was Isaac Heslop). The elder David Blair reportedly arrived in Fredricksburg from Britian and established his business in 1762. He reportedly had 2 sons (David, Jr. and James) and 2 daughters (Margaret and Elizabeth).
