Hello Shona I am the son of John Pressley who is the son of Vida Duthie from Peterhead.
I have some information concerning the family history if we are talking about the same family of the Duthie clan. I do not have any history for my grandmother's siblings but know her father was James Duthie born Peterhead 22 November 1862 died Peterhead 24 May 1941.
He married Isabella Farquhar Center.
I have some other details if this is the family you are seeking.Please email me
