Llan and its variants are a common element of Celtic placenames in the British Isles and Brittany, especially of Welsh toponymy. In Welsh an name of a local saint or a geomorphological description follows the Llan morpheme to form a single word: for example Llanfair is the parish or settlement around the church of St. Mair. Goidelic toponyms end in -lann.
Nidan was a Welsh priest and, according to some sources, a bishop, in the 6th and 7th centuries. He is now commemorated as a saint. He was the confessor for the monastery headed by St Seiriol at Penmon, and established a church at what is now known as Llanidan, which are both places on the Welsh island of Anglesey. He is the patron saint of two churches in Anglesey: St Nidan's Church, Llanidan, built in the 19th century, and its medieval predecessor, the Old Church of St Nidan, Llanidan. Midmar Old Kirk in Aberdeenshire, Scotland, is also dedicated to him: Nidan is said to have helped to establish Christianity in that area as a companion of St Kentigern. St Nidan's, Llanidan, has a reliquary dating from the 14th or 16th century, which is said to house his relics.

A church is said to have been founded here by St Iestyn in the 7th century, with the earliest parts of the present building dating from the 12th century. The church was extended in the 14th century, with further changes over the coming years. It contains a 12th-century font and a 14th-century memorial stone to Iestyn, from the same workshop as the stone to St Pabo at St Pabo's Church, Llanbabo.

Elaeth was a Christian king and poet in Britain in the 6th century who is venerated as a saint. After losing his territory in the north of Britain, he retreated to Anglesey, north Wales, where he lived at a monastery run by St Seiriol at Penmon. Some religious poetry is attributed to him, as is the foundation of St Eleth's Church, Amlwch, also in Anglesey.
St Eleth's Church, Amlwch is a parish church built in the Neo-classical style in 1800 in Amlwch, a town on the island of Anglesey in north Wales. It stands on the site of earlier buildings, with the first church here said to have been established by St Elaeth in the 6th century. Increasing prosperity in the town through copper mining during the 18th century led to the construction of a new church to serve the growing population.
St Fflewin's Church, Llanfflewin is a small rural church, situated by a farm in Anglesey, Wales. The first church on the site is said to have been built by St Fflewin in 630, but the present building has no structural features dating from before the 18th century, although the church has a font from the 14th or 15th century and part of an inscribed medieval gravestone has been reused in a window sill.
St Tyfrydog's Church, Llandyfrydog is a small medieval church, in Llandyfrydog, Anglesey, north Wales.

The oldest parts of the present building are dated to about 1400, with the chancel dating from the late 15th or early 16th century. It is built from rough, small, squared stones, dressed with limestone. One of the windows on the south side is raised to illuminate the pulpit, a decision that in the eyes of one 19th-century commentator "disfigures the building."
St Ffinan's Church, Llanffinan is a small 19th-century parish church built in the Romanesque revival style, in Anglesey, north Wales. There has been a church in this area, even if not on this precise location, since at least 1254, and 19th-century writers state that St Ffinan established the first church here in the 7th century.

The current building, which is in Early English style, incorporates some material and fittings from an earlier church on the site, including the font and an 18th-century memorial in the porch.

The churchyard has part of a stone cross dating from the 9th or 10th century, and some gravestones from the 9th to 11th centuries. It is dedicated to St Caffo, a 6th-century martyr who was killed in the vicinity.
Caffo was a sixth-century Christian in Anglesey, north Wales, who is venerated as a saint and martyr. The son of a king from northern Britain who took shelter in Anglesey, Caffo was a companion of St Cybi, and is mentioned as carrying a red-hot coal in his clothes to Cybi without his clothes getting burnt. After leaving Cybi, Caffo was killed by shepherds in the south of Anglesey, possibly acting in retaliation for insults Caffo's brother had paid to the local ruler. The area where he died has a village, Llangaffo, named after him, as well as the parish church of St Caffo, Llangaffo.

St Llibio's Church, Llanllibio is a demolished church in Anglesey, north Wales. Founded by Llibio in the sixth century, the church served a small community of bondmen as a chapel of ease. The population of Llanllibio declined substantially during the Middle Ages as a result of the Black Death and changes in farming practice, amongst other factors, and the community that the church served effectively disappeared. As a result, St Llibio's closed in the seventeenth century; the remaining worshippers moved to another local church.
The Old Church of St Gwenllwyfo, Llanwenllwyfo is a medieval ruined church near Dulas, in Anglesey, Wales, perhaps built in the 15th century to replace another church from which only the 12th-century font survived. Dedicated to Gwenllwyfo, a 7th-century female saint about whom nothing else is known, it was used as a chapel of ease for the church in Amlwch, about 5 miles (8 km) away. Restored in 1610 and again in the 18th and 19th centuries, it contained an oak screen and pulpit from 1610.
Gwenllwyfo was a female Christian recognised as a saint. She is commemorated in the dedication of two churches near Dulas, Anglesey, in Wales: St Gwenllwyfo's Church, Llanwenllwyfo and its medieval predecessor, the Old Church of St Gwenllwyfo, Llanwenllwyfo, which is now in ruins.
Cynfarwy was a Christian in the 7th century about whom little is known. He was venerated by the early church in Wales as a saint, although he was never formally canonised.

His feast day is in November, although the date varies between sources.
St Edwen's Church, Llanedwen is a 19th-century parish church near the Menai Strait, in Anglesey, north Wales.

It contains some memorials from the 17th and 18th centuries and a reading desk that reuses panel work from the 14th and 17th centuries. The 18th-century historian Henry Rowlands was vicar here, and is buried in the churchyard. The church is on land that forms part of the Plas Newydd estate, home of the family of the Marquess of Anglesey since 1812 and owned by the National Trust. Some of the Marquesses of Anglesey, and some of their employees, are also buried in the churchyard.
