Hi Pete
                    Thanks for that info. I,m still confused. Do you know if the Townsend Thomson  in marriage records as marrying Thomas Scott (myGGG grandfather) in Leslie on 15/5/1853 is your Townsend. 
? I can find some records of Jane Thomson,s around same birth date as the one I,m looking for but wrong mother and father.  I can find no jane with father robert thomson and mother Mary Millie., So---
I have a Janet Thomson b to Robert Thomson and Mary Millie in Markinch on 21/2/1830,  christened on 23/8/1830.(family search.org)  Could she also be called Jane with the addition of Townsend as middle name.?  
I have found a Townsend Thomson b Leslie on 19/4/1831, father John Thomson mother Euphen Burt.
I have a Thomas Scott d 31/5/1899 age 67,  married to Jane Townsend Thomson. 
Jane Townsend Thomson widow of Thomas Scott, died 4/8/1914, age 83. F Robert thomson. M Mary Millie. This would make her birth year 1831 though, not 1830 as Janet,s is.  
In 1861 census Thomas Scott in Prinlaws, Leslie along with wife Townsend Scott and a few children. Also a Mary Thomson--sister-in-law do you know of her?
I cannot pin this down. Is janet really Jane Townsend Thomson.  ?
