A Lonnen is a long road similar to an avenue but without the trees.

It is found in street names in Northumberland such as : Two Ball Lonnen in Newcastle.

Felton is either a place name or a name used by locals to name a street, road or avenue

It is in common use in North East vernacular.

Tappy lappy doon the Lonnen. Etc., etc.

Hope this is helpful. George Henderson.
