I have no clue if your still using this post.. i just happened to come across it looking for my webpages to see if any of them came up with the Meta Tags yet. but anyways. On to what Your Last Name means. Feirn means the verb "to celebrate." Oddly enough Feirn and Feier are some how in the same. but you never use feier alone. now the next word "tag" means day. fairly original. Like Guten tag.. meaning Good day. or hello in english. When people in german say Feiertag they are saying "day of celebration" Wir haben eine Feiertag. Feiertag is not to be confused with Fritag. wich means Friday. I hope this helps you out a little. i'm a little rusty on my german. but i hope that helped you a little in knowing what yours and my last name means. have a great day!
