? Currie is a placeholder for the father of John Currie, whom current genealogical research has not uncovered.
The Currie name has numerous origins. 
Given the proximity of John Currie's birthplace of Galashiels to Midlothian, it seems likely that in John's line the name arose as a habitational name, derived from the village of Currie, Scotland. .
The name of this former village has two possible origins, according to Wikipedia:
There is no accepted derivation of the name Currie but it is possibly from the Scottish Gaelic word curagh/curragh, a wet or boggy plain, or from the Brythonic word curi, a dell or hollow.— Wikipedia
