Frances and Nigel - thanks for your help so far.

Based on your information, I wonder if "Yeigh" means something like goose, but not exactly derived from "guiy" The reason I say this is that I have found the name referenced 3 distinct times in a Celtic ballad or poem. I have had both Welsh and Scottish friends indicate it is some other form of Celtic - I was hoping perhaps Manx? The poem is below - do you know someone who could advise what the text might mean?

1 Hrogg eh e hie.
2 Cha roie my voddey 'sy thie.
3 Chloie ny guillyn ayns e vattey ? chloie.
4 Dobbree yn cabbyl beg jiu ? Dobbree.
5 Nagh ghrapp oo ny billjyn shen ? Cha ghrapp.
6 Cha ren ad yn caashey Jerdein. Nagh ren ad ?
7 Cha yeigh oo dty unniag.

19 Nagh yeigh oo yn dorrys riyr ?
20 Chionnee shin tree billjyn beggey ayns Rhumsaa jea.
21 Chlioe ad ayns shoh Jemayrt.
22 Deeastee mee ayns y cheayn moghrey jiu.
23 Cha dobbree mee ayns my hie moghrey jiu.
24 Honnick mee y baatey faagail Doolish.
25 Dooyrt oo shen jea.
26 Ghow eh yn lioar lesh.
27 Cheayll oo yn skeeal Jemayrt.
28 Va mee troggal yn shapp moghrey jiu.
29 Row shiu baghey ayns Balley Chashtal shiaghtin shoh chaie ?
30 Va shin cloie er y vaatey.

FYI, There are about 50 Yeigh's in the US and Canada all eminating from a John Yeigh who shows up in central Pennsylvania about 1750. We thought he might be of Scottish orgin, but we can not find any reference to the name in Scotland. The above poem and the Loughlan-y-Yeigh are the first Old World clews to the origin of our name. I live outside London so a visit to the Isle of Man is not out of the question.

Again many thanks, John
