Pictish to Punjabi

I decided to make my postcard based on languages of the British Isles. Most of my project has been focused on foreign languages, but I thought it might be interesting to note the languages we have here that many people are ignorant of. These are languages, not dialects or accents.

A quick bit of research found that the below native languages are currently spoken in the British Isles:

English (59,600,000)
Scots
Lowland Scots
Irish Gaelic
Welsh
Scottish Gaelic
Cornish
Manx Gaelic
Jersey French
Jerriais
Guernesiais
BSL

These are the major immigrant languages spoken in the British Isles:

Bengali
Punjabi
Urdu
Welsh Romani
Romani
Sylheti
Cantonese
Greek
Italian
SW Caribbean Creole
Gujrati
Kashmiri

These are the extinct languages of the British Isles:

British
Cumbric
Galwegian Gaelic
Old English
Yola
Middle English
Norn
Manx
Auregrais
Pictish

..and finally languages that once existed in the UK but are now only spoken abroad:

Breton
French
