[6] The parish, originally placed in the ancient Hundred of Dungleddy by the Laws in Wales Acts 1535-1542, and before that in the pre-Norman cantref of Deugleddyf,[7] was considered a suburb of Haverfordwest as long ago as the mid-19th century, at which time it had 1,105 inhabitants,[8] but was still referred to as a village.

[11] The parish church of St David is a Grade II listed building, and has many memorials to distinguished local people.

[12] A Welsh-speaking Baptist Chapel was established in 1858 to serve north Pembrokeshire people settling in Haverfordwest.

It was converted to a paper mill in 1816, establishing the paper-making industry in Haverfordwest, but by the end of the century was disused.

[17] In the spring of 1844, two men were convicted of unlawful assembly in the previous August, and sentenced to 12 months' imprisonment each.
