You are not alone. This has been my brick wall for years now. I am the great-granddaughter of Issac Hohn b. 1943. I have his son Issac as being married to a Mary Beth Thorp.....could this be the same Mary Belle you are referring to? Do you know how many children Issac and Mary had? Issac would have been an older brother to my Grandfather, Robert James Hohn, who was born in 1882. Do you know what year he was killed in the railroad accident? The only information I have on Louis & Caroline Hohn is that they are buried in Long Run Cemetery in Irwin, North Huntington Twp. Penna. The last time I visited a few years ago, it was on a Sunday and there was no one around to get any information from. I have been unable to get back since. There is a church next to the cemetery and I was wondering if anyone has tried to find any information there? In the census records, Louis & Caroline both claim their parents were born in Pennsylvania. After searching everywhere I could think of, I hired a researcher at the Family Research Center in Utah last winter, but he came up empty handed. I have no clue as to where to look next. I just keep hoping someone out there has stumbled on to some helpful information and would be kind enough to share it with us.
