Re. Gulloch---------'Gollick' appeared in the 'Dictionaire Nobilaire' worth taking a look (ancient surname).

(I'm doing Ann Gulloch or sometimes 'Gullock' depending on the "priest" or scribe.

i.e. Ann Gulloch married Murdoch Rosey (Caithness)

Found - Gulloch:- a place in Abernethy, Perth, Scotland see Monnymusk Text.

Other findings --- said to be Norwegian-----not me---though its poss.
Gollach means 'stranger' also poss.
Horny Gollach is an earwig!! So I suppose I can see the 'Viking' connection there!! The helmet/pincers!

I'd prob. go for the Perth connection as the Roseys, they tended to marry in the 1800's, had lived near near Perth in the early 1600's.
Poss. also could be related to the variants of McCulloch etc.
Also poss. is the Norman connection as the Roseys have their name inscribed on the monument at Dives France---and they all tended to inter marry even after centuries had passed. Gollick would appear to be Norman.
Old Norman surnames - family marriages:- Bruce=Rosey
Kennedy=Rosey, Annant=Rosey, Sinclair=Rosey, Grey=Rosey etc.

Quotes from Dict. Nobilaire-(worth noting, otherwise a names list to check when the surname existed).
Note the following from this book:-

'Il n'y a pas de sots noms, il n'y a que de sottes gens. .
Fais honneur à ton nom, et ton nom te fera honneur.

La gloire de nos pères est un dépôt sacré que nous devons transmettre intact à ceux
qui viendront après nous. C'est un héritage que nous n'avons pas le droit de laisser dépérir
entre nos mains , car il ne nous appartient pas.'
I think everyone doing family hist. should read this.

The first time I've seen anyone researching Gulloch other than me! There aren't many left!
