Oh dear, it is as I suspected, I need to find another Alexander Allan. The one I am interested in is Alexander Allan married Elizabeth HOPPS in Lanark, Glasgow on 12 Jul 1872.
They had three children that I know of born Bothwell Scotland.
Jeannie (1873), Alexander (1874), and Helen (Nellie) (1880) before emigrating to New Zealand. There may be more children born in New Zealand.
Jeannie (Jinnie) married Francis Thomas (Frank) MABEY in 1897.
