Old Family Land Line

Note: the number would be from the 1960s. 

Best suggestion I can think of is see if your public library has old phone books.

I googled old phone directories and found this.  You might try it with the city and state you're looking for. 

We are here to help with your landline, @carlapelliott.

Thank you to @spoom2 for the useful information.

As he suggested, we recommend using his link to look up the phone number that you are trying to find.

Let us know if you have any other questions or concerns.
