wow, these are great news.
i didn't know that charles left any descendants.
it's a bit complicated, your g-grandfather charles was one of two children out of mary kocarniks first marriage. charles birthplace is written down as PRAHA, BOHEMIA in WorldWar-Draftcard.

i've got a lot to tell if you are interested. contact me via e-mail : dennis@slanker.de or facebook 'dennis w. slanker'. would be great to hear and share some information with an far-far-away relative! ;-)

by the way, upcoming september i'm making a genealogy trip to new york. i'm in touch, and i'll meet descendants of your g-grandfather's brother, frank kocarnik.

would be great to hear from you.
best regards from germany.
