Daniel was/is common and whether it could have had its origins in the Scottish immigration in the 1600-1700's?
Not at all rare. There are about 4200 people with that name, scattered all over Poland:
I doubt that the surname is restricted to a single genealogical line. You would have to have solid documentation of whether YOUR PARTICULAR line had its origins in the Scottish immigration in the 1600-1700's. The name itself is not to useful here. You need actual genealogical records for each generation back until that time.
