Orphans, Foundlings and Bastards

Whilst there is a veritable myriad of "family" name naming conventions - typically, very young orphans (or foundlings in some quarters) are nameless.
Bastards, are also named by a location (usually street, lane or alleyway) near their place of birth (or conception).

Naming Traditions

Other names

Orphans, Foundlings and Bastards if otherwise unnamed will usually assume the surname of the street they were birthed, conceived or found in.
Many also just use the identifier "Street/er", "Lane", and the name "Way" appears occassionally.
Some also have been known to combine the name of the street or lane, Cordeux Street (in Bannockthorpe) the hyphenated surname would be Cordeux-Streeter perhaps, for effect of course.
