In my 25 years of research I have found that there is little proof of the origin of the Lingo name but many possibilities.Lingoch, Lingow, Lingoe from Scotland and England, Lingot from Northern Italy, and a Lingones and a Linqueux (pronounced Lingo)in FranceI also find the ones in Scotland and the ones in England are very important to us.
Here is my theory.When the Romans moved out of Italy into Europe there was a Celtic Tribe in Gaul called the Lingones, located at what is now Langres.They realized the strength of the Romans and allied themselves with them.The Lingones were mercinary warriers working for the Romans.This would explain why the name is spread all over Europe.There is a record of a community of Lingones/Romas soldiers who settled and stayed in York, England when the Romans left England.
I have done research on the -ch and -nes on the end and found two explanations.One is that they were exclamations on the end. The other is that the -ch is a syncopation of ish, such as French and Scotch which is possible.The -nes is old English or Celtic and means a state, condition, quality, or degree (similer to goodness.
So the Lingo family in England took their family name from the Celtic tribe of which they were either a part of or descended from.Although we cannot trace a specific family member I beleive that we can say that we are Lingones and learn their history of which we are a part.I have no proof of this it is just my deduction from what I have found.
P.S. I have also found a story of how a Portugeese sailor washed ashore in Scotland after the Spanish armada was sunk and they called him Lingo decause of his different language.?????????
