surname field contains a name that is used for sorting and grouping. It can be different to the individual’s actual surname which is always taken from the name field. This field can be used to sort surnames with or without a prefix (Gogh / van Gogh) and to group spelling variations or inflections (Kowalski / Kowalska). If an individual needs to be listed under more than one surname, each name should be separated by a comma.') ?>
