Leigh, One daughter of William and Helen was Amelia Duthie (my line) who was born feb 18 1800 in Aberdeen and died ther in 1855. She was married to a William Walker. I don't think she was a sister of your Duthie 'mother'. But it is a coincidence, which may be inetresting. Do you have anymore on the Duthie family or any known connections to the Walkers of Aberdeen?
