I'm sorry, but I really don't have any info on the Troendles, other than what Fran Haas gave me. I was hoping to learn about Mary's husband's grandparents by searching her out. Fran has numerous messages posted at ancestry.com, and maybe rootsweb also. I believe it was ancestry's free message board that I found him. He and another man have a good amount of info. You might look there, he responds pretty quick if I remember right. He could help you much more than I can. He has the name Silas also. Good luck!
