Yes, John Nisbet of Ayton Mill has always been my bet for Euphemia's father.
There is a lot of circumstantial evidence to support this:
5. Euphemia named her daughter Alison, John's mother's name, in the proper place in the naming convention. No Alisons in Dickson or Shiels direct line.
The evidence against:
1. Geographical location of Agnes Shiels and John Nisbet.
2. John had three young children with Margaret Bell at the Time of Euphemia's birth.
It's a close call.........
