This is all of my first cousins except two, who were not yet born when this photo was taken. In the back are Kelly and JP Heydle, Laura Lowry, me, my sister Caroline, Michael Lowry, and Katie Lowry. On the slide are James Lowry, Sara Lowry, Jeannie and Jen Kroynovich, my sister Colleen and Kaitlyn Lowry. It took me typing this caption to realize that we are all arranged in order of age. The youngest person in this picture, Kaitlyn, is 23 years old, making this photo about 20 years old.
