Hi all,

First time posting. My great-grandfather Alexander Mallis MacGregor, I was told owned MacGregor mercantile shop. My family told me it’s still in the MacGregor family. I’m looking for any info on my great-grandfather and the shop. Also, if anyone may know how to research his ancestors in Thurso Caithness, Scotland. Can anyone please explain Caithness to me? Any other info is greatly appreciated! I live in Denver, Colorado. Thank you Mike
