The Spanish generally have two surnames (first surname of father + first surname of mother), unhyphened. What is the protocal on Wikitree for introducing them into a tree? I have used a hyphen for my wifes surnames (although this is not done in Spain), as well as for my childrens name (as here in NZ they officially have a hyphen). I have seen a few others on this site apparently using an underscore between the two surnames. Obviously how they are introduced will affect searches and create the potential for unmatched duplicates.
Many thanks,
Steve
