I think it is important to get your children involved in Family History Research. My grand daughter have called for information on our family history because she needed it for a class assignments. When she visits me during the summer, she often make trips with me to the court houses and libraries here and in surrounding counties.
When my grandson begin learning his alphabets he started going with me to cemeteries. He would call out the letters on headstone for me and he has enjoyed it so much. I love doing the research and hope that when I am gone, my children or grandchildren will continue the search.
