How do you determine gender of first name

Before doing a lookup query against our database, our algorithm performs multiple transormations on the requested name to match every possible variant of it. It gave better results for multiple words names, non utf8 characters, or names including special charaters and numbers.

Do you determine name by country or ip address

We have decided to ignore the geographic and cultural aspect of first names, because of the melting of cultures around the world and global migration. The gender types we have: male, female, unisex "where the first name can be both used for male and female".
