I have some information about this family, passed on to me but not relating to my own Liddell research.
Andrew was born in Paisley, SCO 1842 and Ada in Wiltshire, ENG 1856. They had 7 surviving chn out of 14 births. They lived in New Zealand in Woolston and later Winton.
I am happy to share it if anyone is interested in this line.
Cheers
Cherilyn
