The following are source information for a variety of documents held at the National Archives of Scotland.
There seem to be 3 generations of John Lothians listed here.It is a little complex though. A tidesman (tiesman) is a merchant/maritime customs tax collector. I am unsure if John moved from Alloa and his offspring moved back and then to Jamaica.Or hif he is a part of the Kirkcaldy Lothians who moved to Alloa, and then to Jamaica.

I have written a family history that includes part of your family if indeed the John Lothian above is related to our family.
The reasons I think that he was are: -He too was a merchant. as were our family. -He was also a baillie, as were our family. -He shows up suddenly in Burntisland, two parishes away, just after the Kirkcaldy economy crashes in the late 1600's/early 1700's.
If he is a part of the Alloa group of Lothians, I think you will find that they too were wealthy merchants involved in maritime, although that is only an assumption.
Hope this helps,
