I'm writing a story set around 100 AD in Roman Britain and am trying to find authentic Celtic names for some of the characters. This includes characters from all tribes across Britannia so any and all names are welcome.

I am from Bosnia and i am a Slav (mostly), but i also have Celtic,Gothic and Illyrian genes. I live near the biggest Celtic and Gothic archeological site in Bosnia. So i am wondering about Celtic traditions to see if there is anything left from it in Bosnia.

Bit of a random question but does anyone have any clue as to why whenever there is a show or film set in the Old Old eras of Britain its always focusing on Vikings invading and never bothers with Celts fighting off romans and defending the coast or hell when the vikings and celts butted heads? idk feels like they're being sidelined or have I just missed all the good Celtic stuff?

(Bonus question. Why do the vikings in "How to train your dragon" have Scottish accents?)

I’m just wondering if the celts were the first to really settle down and create a society in Ireland, or if there were previous groups of people in the land

The kind that pins at the shoulders. It’s for multicultural day at work. There’s no contemporary Celtic dress so I’m going old school with a white and blue plaid flannel sheet as my fabric. Yes I know ancient and modern plaid are different but I’m on a budget and a deadline.

Is it just a tube of fabric pinned at the shoulders and belted at the waist?

I'm not sure which Celtic language of the 6 surviving ones to start with because I eventually plan to learn all the 5 others and later on delve into learning what we know of for the ancient extinct tongues since my primary reason for learning Celtic languages is because of an on and off interest into ancient Celtic religions due to a paranormal experience I had years ago which I prefer to keep confidential.

So which of the still existing language is the best foundations to gradually go into learning the others and eventually graduate into ancient and now extinct languages only known in functional form because of academia and scholars?

Several grave goods found in Stična, Slovenia, from the second half of the 8th century BC, Hallstatt culture. This photo was taken by myself at the National Museum of Slovenia.

They look like big skirt or safety pins. Like what this display has. How do I find/make some?
