The Wilsons were protestant , On scottish records and census thats where this Shinn comes from. I beleive you are right with the 1869 and Hans was a brother, Also he seems to have had another brother Samuel who lived in the same row of houses in Netherton New Kilpatrick doing the same job so maybe Samuel got Thomas the job at his brickworks, Thomas was a lodger with my gt,gt,gt grandmother and my great grandmother lived with her. Thomas got her pregnant and the rest is history. he beat her every time he was drunk which was often.
