Hi there I am researching my family tree, I am from Australia. Here is the iformation I have of the Millers in my tree, I would be so glad to hear of any one who is a reli and may have some information to share with me! 
I am the great-grandson of
Frank Cormack who "went to USA". He married
Dora Waters, had two children, then moved to Colorado, USA and had six more including the youngest, my grandmother. I was in Wick last August and did a bit of research, but mainly on the McIntosh and Cormack branches.
I also have a
Donald Miller in the tree (d. 1927?), who married
Christina Waters (1863-1912, sister to Dora who married Frank Cormack). So there might be a connection via Waters as well as Cormack.
