Hi Steph, Just by chance I was googling my family history and I came by this post. I think we may be related. I remember my dad telling me a friend had helped with his family history and the first Macari's in Scotland were an Italian couple called Luigi and Guiseppina.
I live in Australia. My Dad Paul was born in the UK to Lilian and James Macari. James is Scottish Italian. My dad has an older brother Alan. They currently reside in Fife. I plan on visiting this September. I don't know much about my family history on my Pops side but I'll ask and see how far back he can go. I also know we are somehow related to Lou Macari, who played for ManU. I know you are probably more interested in the older family history, but figured I would say hi.
Your post has certainly peaked my interest in finding out more about my history!
