David, I have a lot of info on the Elser line going back to Michael who came from Germany. If you would like I could send it to you, but there is a lot so maybe you would like to contact me at "firstname.lastname@example.org". Are you interested in just your line or the whole family?My mom is Arline Elser and her dad was Lewie Elser. They were in Defiance County, OH. Lewie would have been an uncle to Harry. Where is Johnston OH? I was just in Ohio on my way to PA in July and we stopped at the cemetaries and took some pictures.
