Tal-y-llyn is the name of a former township on the island of Anglesey, north-west Wales. It was located about 4.25km (02.64miles) to the northeast of Aberffraw.[1] In 1306, when a survey was carried out of the lands held by the Bishop of Bangor, Tal-y-llyn was recorded as having three free tenants, who together had about, and nineteen unfree tenants, who held about between them. This would suggest a total population for the community of 110 individuals. However, the population declined in the fourteenth century, the period of the Black Death.[2] St Mary, Tal-y-llyn, the chapel of ease that used to serve the community, remains. The oldest parts of the church date from the twelfth century. St Mary's, which is a Grade I listed building – the highest grade of listing, designating buildings of "exceptional, usually national, interest" – has been in the care of the Friends of Friendless Churches since 1999.[3] [4]
