Another note: Ballygrant was the center of an active lead and silver mining industry in the 17th, 18th and 19th centuries. There were at least four productive mines in the area. In 1880, mining came to an end there with the production of 38 tons of lead and 1,214 ounces of silver.

Might the original line be "With lead and silver I did support her"? It could make more sense and help date the song. Just a thought...
