Hi Shari,
Sorry, but my research was not extensive enough to cover that and I'm no longer researching in that area.
I would suggest you approach Tony Gott at
http://www.bayanne.co.uk/Genealogy/Gene.html as he holds a great deal of information and would be in a better position to help than me.
Coincidentally, I expect to be in Shetland on holiday at the beginning of October.
You mention gypsies. Are these true Romany Gypsies or just Travellers?
Good Luck with your research,
James.
