Hello Melanie, I have a post card signed by a Alonzo CLARK in 1910, in Anderson Madison Co., IN.. Might this be your Alonzo ? Marcie in IN.. In our family we have an Alonso, but ours was born about 50 years later. But that's very unusual, that you have an Alonzo, and so do we? I'm really wondering if there isn't a connection......???
