Hello Rory
I am descended from the Ferry Port on Craig, Fife, Dutches. George Dutch (born 6 March 1801) was my GG Grandfather and George Dutch before him (born 11 May 1760)
my GGG Grandfather. I have information on that line - from memory two brothers came out to NZ (maybe at different times) One on Lady Edigia - I'll have to look it up. If you think this is your line let me know

cheers and good luck
Lynne Anderson
