Emigration from Liverpool on the ship The Henry Clay to New York 1846

This poignant letter and lock of hair tells part of the story of the emigration, from the port of  Liverpool on the ship The Henry Clay, of Thomas Tait and his family.  Probably a Scottish family Thomas Tait sends a lock of his ?daughter's hair via a Mr.Wm.MacKinlay to her grandmother as the family were to sail the next day. It is sad that no more is known about this family, and no news either whether they even set off because it is known that the ship The Henry Clay was ship wrecked off the New jersey coast during March of the same year (1846). The letter mentions the  sailing would be on the morning of 23rd July 1846.
