Hi,You might try the spelling of the name Wolford to the spelling of Wolpert or Woolford.Since I have been doing data entry for Family Search. com I have learned that the cenus taker often spelled names how the sounded rather than actually spelling.The spelling of name is fairly consistant.All will get you the info you need.
Just for your info. I am the Granddaugter of Emma Woolfred of New Jesrey.
If I can be of further help e-mail me. My email is email@example.com.
