Do you have an address book? Have you inherited an old address book from your parents or grandparents? This is almost as good as discovering an ancestor's journal.
Will Kenny, wrote a post for Minnesota Public Radio (MPR) - Address book is a family history, bound by tradition - in which he writes:
....And this annual ritual recently reminded us of a big difference between pulling out a physical, paper address book and pulling up a contact list.
These days, if you keep your contact list on your phone or your computer, you live very much in the present. When you update an entry in your electronic contact list, you just edit the information. You replace the old with the new.
And when people are no longer connected to you, whether you somehow lose touch or they pass away, you merely delete them from your list, and from your life. At the same time, you delete a piece of your own personal history.
Diane Richards wrote a great blog post in Upfront (the National Genealogical Society blog) on her own use of these hand-written resources for family history, who writes that she is on her third one (begun in December 1998). Earlier ones now live in her "memory boxes." She also shows examples from her latest address book.
