Leave a note
Something else that sometimes works is to print up a bunch of notes (the size of the zip lock type pint bags) containing that same info we include at the libraries and research centers. Stuff the little note in the little plastic bag and anchor with a rock at the headstone of each family member. One of mine waited patiently at the grave for four years before someone came by and responded. Four years for a little info was no time compared to having nothing and never getting it.

Take 3 x 5 cards with you to libraries and ask whomever is available where the family research card file is located. You can include any info you wish. I don't stay at home so I generally don't leave my landline, but snail and email works great for me. Even though I am in touch with people who don't have email; I have been put in touch with them by someone they know who does have email. They saw my card in a file and had a friend email me. The post office is a very slow way to communicate now that most of us are on the Internet and brings back long ago memories of sending a letter and getting a response six months later. By then I would have long forgotten the excitement I originally had.

The cards usually include your full name and all methods of communication. For women and security, leave off the maiden name and just mingle it in with the surnames.

Include all surnames.

Include full names of people from 100 years ago and older. On those, include birth and death dates and places. I don't tell the Internet who my parents and grandparents were. When I get to the suspected 'shirttail' cousins I then share more detailed info. Shirttail are very distant cousins.

By now, your card is fairly full so finish it off with fact and oral history. Keep it concise and cram as much identifying info in there as you can."
