Coincidentally, I live in the area and have McClurg ancestors (but mine are from Northern Ireland!)
From my own research, I would say the McClurgs may have originated in the far south-west of Scotland.From there some sailed across to Northern Ireland - where there are still McClurgs today.Some seem to have moved northwards towards South Ayrshire and beyond.There are very few McClurgs (of either spelling) in Scotland today as many families changed their surname to McLeod in the 19th century, making them hard to find.
