Tami I will have several Alexander and Archibald Nivens contained in various Trees I have compiled. As a flavour I have Archibalds in Ochiltree and Greenock There is an Alexander died in 1806 in Oddington near Oxford I am keen to find his ancestors - supposed to be from Ayrshire. He has interesting descendants. There is an Alexander b 1760 - Bishop of Dunkeld - several generations of Alexander followed. Alexander Thomas b 1830 had a great grandson John Ballantine Niven, killed in the World Trade Centre in 2001. This family originated from Girvan. If you can give me some more information I may be able to help.
