I tried sending the following message to your email address but it was sent back so I will post it here in hopes that you can get to it. Let me first say that I find your name interesting, my younger brother is Corey Michael Tost and other than him I had never heard of another one. Anyway, I do have information on the Tost family that I would be more than willing to share with you.
Let me start at the beginning, William Fredrick (Wilhelm Friedrich) Tost was born in Kreis Bochum Wanne Westphalia Germany in 1849. (the word Kreis in German is similar to our county so it would be seen as in the county of Bochum, the city of Wanne in the state of Westphalia Germany.)He immigrated to the United States in or around 1872 (I believe I do have his naturalization record somewhere).He was married to a woman named Annie Ludwig also from Germany and the couple settled in Jefferson County Pennsylvania in a town (which no longer exists) called Ramseytown.It is between Reynoldsville and Brookville.There is a church there that is still in use and many of the family are burried in that cemetery. (I have paintings of Annie Ludwig Tost and their oldest daughter Lena if you are interested in having me scan them for you) The children of William and Annie were Lena Tost, Oscar Tost, Tilly Tost, Henry Tost and William Tost Jr. They were all born in Ramsaytown and to my knowledge all but William Jr. moved to Indiana County eventually. Lena Tost married John Baldauf and they had four children, Betty, Kathy, Margaret and Sally. Henry Tost had eight children (I don't have the name of his wife listed.) Their names were William Tost, Frederick Tost, Harold Tost, Walter Tost, Earl Tost, Paul Oscar Tost, Henry Tost, and Raymond Tost. (I believe that this is the family that you are looking for.) William Tost Jr. Married Annie Davis and they had five children, William Earl Tost, Edith Tost, Jane Tost, Gertrude Tost,and Hazel Tost. Of these children one is still living Mrs. Gertrude Stewart of Reynoldsville Pennsylvania.You may be able to contact her for more information on the family.If you like I will try to get her phone number for you. As for the other children of William F. and Annie Ludwig Tost, I will have to look through what notes I have here on them.My parents were divorced last year and a lot of things that I had stored at their house got misplaced when they sold the house and went their seperate ways.But I will try to find what I have. In addition, I also have a cousin Kathy Yutzey, she is the daughter of Paul Oscar Tost (Henry's Son) and she was originally from Plumville Indiana County PA. She lives in DuBois Pennsylvania now and I should be able to get her number for you as well. I wish you the best of luck on all your research and please let me know if there is anything else I can do for you.
