It's interesting that Henry called his first and only son Daniel after his stepfather as tradition was first son after dad's dad. Now Daniel was probably the only father Henry knew but it's interesting that while he seems to have claimed his natural father's surname he has not used the forename Henry.
What was Daniel Mathieson's father called?
I think you are correct Henry was born outside marriage but whether his natural father was called Henry Giles or not you might never know. There seems to be a dire shortage in Scotland of men with that name in the years 1851-1861- only the English comedian- and no deaths that I could find.
I wondered if Daniel was indeed his father and the couple married after Henry's birth (wouldn't be the first time that happened)

. How is Henry listed on the Census -son or stepson?
Good luck with your research.
Looby
