How about it - Macks or maybe some Brethren historian. I aked about Macks in Ulster about 1800 - they are reported to have come to Guernsey County about 1804 with the Robert/Alexander Campbell family - I heard nothing so I assume nothing is known in the Mack tribe about a Mack family in 1800 Ulster? This is kind of important becuase if they were there we could search for them and maybe find the otherwise elusive Robert and Alexander Campbell of Antrim. I would appreciate a reply even if it is negative. Thanks Hal
