Hi, I`m a newbie at this game,so any help would be much apreciated

.
I am trying to find a Charles and Laura pexton(nee GILL).
They lived in Sheffield , and I am told they had four children,
a. Ruby
b, Douglas dob 12/02/1917
c, Jack
d, ?
Charles was a joiner by trade.
I don`t know if Charles originaly came from sheffield,as I don`t seem to be getting anywhere at the moment, as without his birth date I can`t connect to the family tree.
cheers Ian
