Shiraleee on Family Tree Circles

Hi all my great grand mother's name is Margory Taylor Younger and my great grandfather's name was William Wilson. As far as I know my great grandmother gave birth to a son called John Wilson on the 20 Apr 1881 St.Andrews & St. Leonards, Fife, Scotland
I was told she also had another child Just after giving birth to my Grand Father which later died. she also died during the birth of the second child. My problem is I cant find her or her husband on any of the census listing ither the one b fore 1881 or the one in 1881. If any one can help me it would be much appreciated. cheers Shiralee
