John, Were the family in Scotland in 1881? as I have'nt been able to locate them yet.
I found these on familysearch, some children of John and Jane.
1. CHRISTINA WILSON - International Genealogical Index
Gender: Female Birth: 25 DEC 1855 Coldstream, Berwick, Scotland
2. ELISABETH WILSON - International Genealogical Index
Gender: Female Birth: 16 AUG 1857 Coldstream, Berwick, Scotland
3. JOHN WILSON - International Genealogical Index
Gender: Male Birth: 03 MAY 1862 Coldstream, Berwick, Scotland
4. FANNY WILSON - International Genealogical Index
Gender: Female Birth: 29 OCT 1860 Coldstream, Berwick, Scotland
Chrstina's birth cert. of 1855 will give you her parents age and where they were born, but may be registered under the year 1856 as she was born on Christmas day. This would narrow it down on where to look for their births.
