Hello Mary,
Although your James Goldie, was born 8/0ct/1846. i dont think his parents Robert Goldie, and Jean Fulton, were married.
Jean Fulton, then had a child William Brydon, 14/April/1849. to father Thomas Brydon, all this in Kilwinning, Ayr.
By the 1851. census. in Kilwinning, Jean Fulton, is living with her widowed Grandmother Isobel Miller, also her sister Ann Fulton, and the two boys James Goldie, and William Brydon.
By 1861. Jean, is in Kilwinning, with her new husband Samuel Bonner,
Bonner Samuel, age 37 years, born Govan,
Bonner Jane, age 34 years, born Kilwinning,
Bonner James, age 15 years, born Kilwinning,
Bonner William, age 12 years, born Kilwinning.
Jane/Jean, has trimmed quite a few years of her age in 1861, and the children called Bonner, cannot possibly be Samuel Bonner's, children.
It would be quite interesting to see what the births of James Goldie, and William Brydon, state on their birth certificates as regarding their rank of birth, because i dont think Jean Fulton, was married to either of the fathers.
Regards,
Jonn.
