Ffynnongroyw (sometimes spelled Ffynnongroew) is a village in Flintshire, north Wales. It is situated on the A548 road, near the Dee Estuary coast, near Prestatyn. The name Ffynnongroyw is from the Welsh word "Ffynnon" meaning well and "groyw" meaning clear or pure. The original well is still in existence and is situated on Well Lane in the village. Nearby is the site of the old Point of Ayr Colliery which opened and developed in the late nineteenth century. As a result the population of Ffynnongroyw grew considerably during this period with people migrating there from many different regions of Wales and England. Before the Colliery opened the village was all fields with only a few little cottages.
