Missing Cousins/Photos

[nooshie]

I am a board member doing my family tree and know that my dad's cousin had some photographs of ancestors.  She lived in Oundle in the 70's early 80's and moved to Cambridge (perhaps) after divorce.  She was named Heather Smith (I think, maiden name Stringer or Springer possibly) and had children called Robert, Charles & Bridget and two others.  I am desperate to contact her as these photos are paramount to my research - anyone know anything?  I know its a longshot.
