Do you remember the children's song about the bones in your body being connected? "The hand bone's connected to the wrist bone, the wrist bone's connected to the arm bone..." and on it goes about "Dem Bones". That's pretty much describes my hobbies.
It formally started when I was attending college. I suppose the fact that I was in my 40's was one reason why this caught on with me. We had to do a paper about our heritage. So I pulled out the information my mother assembled years earlier (when I didn't care a wit about it) and wrote an essay about my parents and grandparents. I think from that point on, I was hooked. I became known in the family as the one who knew how everyone was connected. Next thing I knew, I found myself looking for genealogy software. I had to get this documented!!
My photography hobby? Easy...I want to be sure that my life and our family history is documented. I want to be sure that when my grandkids pick up pictures, it tells who is in the picture and what the story is behind that picture. I want to be sure that the generations that I won't meet will know their past. The best way is in pictures (with journaling).
