If that is the couple then they were born before 1910/1911

There are a number of children possibly born to this couple, but as they may very well still be alive, I am unable to name them.
However, by using FreeBMD, and using the surname Brown and mother's maiden name of Green, plus a start date of 1924, there are some possibilities in the Barnsley Registration District. Sorry, I may be telling you something you already know how to do.
rosie99 and avm228 have given you a lot more information.
