Input: Text: my great grandfather had received the silver star for valor during wwi. i had known this and the fact he came over from poland to join the us military to kill germans always seemed like an honorable thing. he was also 16 when he arrived and said he was 18 just to join. after the war he became a coal miner apparently. i started doing some research online to find out more about him and found someone with his name, the correct age and the right area of the country. they were a gun dealer tied to selling thompson machine guns (not thompson himself) that were used int he st. valentines day massacre. knowing no one in my family had ever told me about this and the guy used a pseodo name leaving off the last part of my last name, i struck out for truth.

i started with my cousin whose mom is the last living child of my great gradnfather. i got no suck luck about being a gun dealer but it shocked me that i was told that my great grandmother died in 1935 by falling off a wagon and hemorrhaging to death. she was pregnant. this seemed perfectly normal for a farmer so i thought nothing of it. desperate to seek out more truth in the whole gun selling category to al capone, i called up my grandmother to see what she may know about it. i didn't think she would know much since she wasn't a child of my great grandfather but was married to my grandpa for over 50 years so she might know something. i asked her about it and she gave me the "i don't know story." i then proceeded to mention the my cousin mentioned that great grandma fell off the wagon and this is where i fucked up... i had my 5 year old son in the room and 10 year old niece. grandma is on skype on the tv and she says, "oh falling off the wagon is what he told people. no he beat her to death and just said that. your grandfather was 10 when it happened."

queue the awkward silence... alright moving on. the answer i got was that it is possible he was the gun dealer because he would have been the right age, the right name, and the right nationality at the time. the events of the gun dealings happened in 1929 and my grandfather was born in 1925. anyways yeah so that it.
