You need to go to
www.scotlandspeople.gov.uk and view the image of the original document to see what you think it actually says. It's pay per view but modestly priced.
You can also view the baptisms of Esther and Robert Hay and see what other information might be on the original. There are Robert, baptised 15 March 1835, and Esther, baptised 25 December 1836. Looks as if the first Robert must have died and a younger child whose baptism record has not survived was given the same name.
