I figured I would do this for all the Flyers from North America:
Mason: English. Most common around the North and Midlands.
Emery: English. Most common in the West Midlands. Though it is also a common-ish name on the French-Swiss border. But England is 90% more likely.
Zepp: German. The name originates I believe from near present day Luxembourg.
Coburn: Irish. More eastern Irish and Northern Irish than anywhere else.
Schenn: German. Name is very southern German/Austrian. Not really found outside those areas with frequency.
Schultz: German. But very 'Northern' German. Name is actually more common in Southern Denmark.
Del Zotto: Italian. More specifically a pretty 'Venetian' or 'Friulian' name.
Colaiacovo: Italian. Maybe Abruzzian?
Manning: Irish. Quite Western Irish.
Gostisbehere: French. Very Southern French and super rare.
MacDonald: Scottish.
Giroux: French.
Simmonds: English. Very Southern English name.
Couturier: French.
Read: English. Southern English specifically.
Umberger: German. Name seemingly originates from near Stuttgart.
Lecavalier: French.
Laughton: England. Yorkshire and the East coast seems most likely.
VandeVelde: From what is now Belgium in that form. Could also be Dutch and they put 'van de velde' together. Means 'from the field.' Belgium and the Netherlands were virtually one and the same for a long time anyway.
Rinaldo: Italian. Hard to say where exactly. Pretty widespread name. Venice area, Calabria and Sicily have high concentrations of Rinaldo's today. I would say Southern if pushed.
Jones: Welsh.
White: English. Very widespread name. But most common in the Midlands and South West.
Akeson: Swedish. Bastardisation of Ã…kesson.
