The sources, particularly the 1851 census, reveal that while Amlwch remained a predominantly local community, it attracted a significant number of residents from across Wales, England, and Ireland, likely due to its booming mining and maritime industries.
The vast majority of residents were born within Anglesey, with many hailing from Amlwch itself or neighboring parishes such as Llandyfrydog, Llanbadrig, Llannerch-y-medd, Llanfechell, and Llanelian. However, the community also drew people from across Wales:
• Caernarfonshire: Numerous residents moved from across the Menai Strait, arriving from Bangor, Caernarvon, Nefyn, Llandudno, and Cricieth.
• Denbighshire: Birthplaces include Ruthin, Wrexham, Denbigh, and Llanrwst.
• Flintshire: Individuals hailed from Mold, Newmarket, Nannerch, and St. Asaph.
• Other Welsh Counties: Residents are also recorded from Merionethshire (Dolgellau, Ffestiniog), Montgomeryshire (Llanfyllin), Glamorgan (Swansea), and Pembrokeshire.
English Migration
Amlwch’s industrial and commercial needs brought in individuals from major English centers and mining regions:
• Lancashire and Cheshire: There was a substantial influx from Liverpool, as well as Manchester, Chester, Altrincham, and Stockport.
• Cornwall: Reflecting a shared mining heritage, specialized workers like Mine Agents came from Redruth, Gwennap, and Germain.
• Southern England and the Midlands: The data records birthplaces such as London, Lyme Regis (Dorset), Bristol (Somerset), and Burton on Trent (Staffordshire).
International and Maritime Birthplaces
The port and industrial landscape facilitated wider geographic diversity:
• Ireland: A notable portion of the population was Irish-born, with residents hailing from Dublin, Sligo, Cork, and Drogheda. The 1841 census even identifies specific work areas like the Brimstone Yard as housing Irish workers
