http://www.hbosplc.com/abouthbos/History/Halifax_Tree/Halifax_Equitable.aspThe Andrew Common and Agnes Curle link was wrong, although they did have an Andrew Common themselves in 1815;
their children are shown as:

Grizell Common christened 22 Nov 1811 Melrose, Roxburgh, Scotland
Margaret Common born 24 Oct 1812, Melrose, Roxburgh, Scotland
