I am doing some research in the parish of Llansilin on the Shropshire/Denbighshire border. I have noticed that a number of the families living there in the mid-1700s are using their father's forename as their surname. For example there is a Lewis Llewellyn and his children are called John Lewis, Anne Lewis etc.
I am looking into a Rice/Rees Edwards. His age at death gives him a birth of cira 1754 and in the parish there is a baptism for a Rees, son of Edward Rees on the 29th of March 1754. The township that Edward Rees is listed as living at is the same as the one Rees Edwards can be found living at in 1788. The name Rees is also uncommon in the area, with the next Rees baptised in the parish coming in 1798.
I am just wondering how common it was for people to take their father's forename as a surname, when their father had apparently dropped the ap/ab in there name. And also, how likely do people think that this 1754 baptism is the right one? As Rees Edwards died in 1839, I have no idea where he was born.
