.there were a few people named easther brown and william tait (my greatgreatgrandparents) in and around belfast at the time they would have been there.both of these people were born around 1815. i have been searching over in donegal, tyrone and derry, though after 8 yrs. of research, i rule nothing out. i have also always understood both william and easther to be presbyterian, scots irish, and alot of the people in conty down and county antrim were english-irish.
