Trevalyn Hospital

A Memory of Rossett.

I was born in this hospital on the 30/09/1955, my name was Derek Jones. After my birth I was adopted in Nov 1955, I am trying to find my birth mother, I have got her birth certificate but can't find if she married or not. I've been out a lot of money buying certificates but can't find my mother as Jones is a common name in Wales. I found my mother's mum, dad and great-grand parents. My mother's name is Lilian Mary Jones born 2 Feb 1934 and lived in 20 Bowydd Street, Blaenau Ffestiniog. Can anyone help me trying to trace my mother please?
