If you are stuck, be sure to give us something to go on. Post what you know of the family, preferably the details of the oldest known person/couple you have: Date of birth, where born, where died, where and to whom married, etc. Just a surname and location is not enough to go with.
If you're already using software, you can also attach a zip file of a Pedigree or Descendancy chart, or even your Gedcom.
Also, see here for some helpful research tips.
