Many thanks for all that information.  From the burial records I got at the library it would appear Agnes FORSYTH was buried at Lochmaben.
Thomas's two sons died very young as did their father and were all in the grocery business.
 I wonder if this was why  Isabella FORSYTH their mother and her daughter went to Lochmaben to live after living at Caerlaverock.
Yes I agree with Lochmaben just quoted what Ancestry transcribed  
 
Not a problem  

.
Both Isabella MEIN (Forsyth) and her mother Isabella FORSYTH were on 1841/51/61 census for Caerlaverock.  James FORSYTH died August 
1860 at Caerlaverock and 8 August  
1860  John MEIN died. So, sometime between 1861 and 1867 both Isabellas moved to LOCHMABEN. Perhaps to be with their family.
