Emma Susan Armstrong/Arnold (not sure of which was her maiden name)married a man with either the last name of Arnold or Armstrong,when her husband passed away, she married Stewart Laverty.She probably was born late 1830's.
When married to Stewart Laverty they lived in Dorking,in Capel,Surrey England,and was listed in the 1901 England Census.
I know there isn't much to go on, I just thought I'd take a stab in the dark. Thanks!
