Hi Lesley.Lynch
The man I think is in the photo is my great grandfather John Christie Wilson born 1854 in Falkirk, his father was William Wilson born 1810 in Muiravonside, Stirling and his father was Charles Wilson who was married to Catherine Clapperton. I cannot trace a marriage or birth for Charles I just know that he appears in the baptism records in 1805 in Larbert, Stirling with the baptism of his daughter Anne Wilson.
I am not sure of the connection to Dalkieth the only possible link is that William Wilson's sister Christina married Peter Ketchen, who was from Lasswade which I think is near Dalkeith. It would be interesting to know if there may be a link between my Wilson's and yours?
