Hi,
I am fairly convinced that the spoon is Norwegian and from Bergen, even if I had my doubts when I read Silverports "verdict".
The name is probably Hameraas (Hamerås /Hammerås).
New York Passenger Lists, 1820-1957 results for Hameraas

The third mark is the town mark of Bergen.

Town mark of Bergen Norway
Norsk Folkemuseum has two nearly identical spoons made in Bergen.

NF.1944-0619 Niels Brynildsen, Bergen
NF.1944-1097 Niels Crispinus Bakke (probably)
I leave the maker's mark to someone with better reference books!
Hope this helps
Best regards/JAKJO
