Marion,
You seem unsure what a beetler and a bleacher did. Linen manufacture was a very big employer in and around Belfast in the 1800s. Beetling was part of the finishing process. A beetling machine hit the linen with wooden hammers. This gave it extra strength and the nice sheen that people liked. Bleaching was part of the process that turned linen white. The material was laid out on greens and the sun bleached it white.

Thank you Elwyn, your right I didn't know what they did.
In Greencastle at that time was the mill and a bleach green.
I live round the corner from where that bleach green was, so the McKernons haven't left the area in 100 odd years.
Thank you,
Marion
