Hi
I am just answering this off the top of my head and I will have to go back to my records, but there must be a connection somewhere. My ancestors were Spirit Merchants in Dumbarton, one Sarah Smith married Peter Kane and had 3 children, Peter, James and Sarah. Both boys and her husband died before 1850, Sarah ran a boarding house in Dumbarton and Sarah her daughter married a William Duffie. He went on to be a publican and died about 1929. He had one son with Sarah before she died and he married someone else whose name escapes me. I have not done a lot of research into Duffie as they were not my direct line, but between spirit merchants, Kane's and Duffie, its too much like a co-incidence. I will not be able to look at my records until Saturday, but will get back to you.
