In my DH's large extended family, there is only one Welsh speaker. None of them learned Welsh at school - it was apparently not an option. I was chatting to a friend of my sister in law about the language thing and she said that there are very few Welsh speakers in the area (Gwent) though there is a generation coming up that will hopefully be fluent in both languages. My best friend was brought up in a village near Swansea and none of her family or friends, nor those in their wider community, spoke Welsh either. Neither she nor her sisters ever learned it. Up in Brecon, where DH's grandmother lived, Welsh seemed to be widely spoken. We lived in Pembrokeshire (known as 'The Little England Beyond Wales') for a while and always heard more English spoken than Welsh in the larger conurbations, but when you were out in the sticks, it was very different. The further North you went, the more you would find Welsh spoken. Just my five penn'orth!
