Hi,
I have just read your posting re the Black family. My granny was Phoebe (Euphemia) Black who married William Burnfield. if you give me your email address I can give you all the information you require. there are pages upon pages. Chrissie McGregor was my mum's cousin, her father Joseph Black was her uncle. I think the Greek connection was all in Chrissie's mind, she also told my sister this, but no trace at all. Grandfather Joseph Black was married to Agnes Munro, whom my mother was called after. his father was married to Mary Currie, whose family were quite affluent in the town during that time. they got married in Paisley and then went to Londonderry where Joseph(Chrissie's) grandfather was born before they came back to Campbeltown
Hope this helps and look forward to hearing from you
Josephine.
