Research by Owen John Thomas shows the historical strength of the Welsh language in Llandaff. According to his book Yr Iaith Gymraeg yng Nghaerdydd c. 1800–1914 (The Welsh language in Cardiff c. 1800–1914), the nonconformist church in Cardiff Road was a Welsh-language church in 1813. His work also shows that Welsh was the main language of the street in Llandaff in the 17th century.[citation needed]
