There is a lot of confused information out there that mixes up my ancestor Isaac Franklin Ressler with an Isaac S Ressler who was also born in approximately 1847, but died in Bluffton, IN in 1905; either or neither or both could be this Isaac Ressler. To be fair, I don't know from my own family sources when or where Isaac Franklin was born or died though 1847 seems reasonable, and they were apparently both blacksmiths, although the Mart Zimmerman "O'er Stormy Seas" book specifically implies that Isaac Franklin (Sr.) was a blacksmith in Manheim Twp. PA, around the time Isaac Franklin Jr. was married in 1898. I had assumed that Isaac Franklin Ressler was the son of Isaac Ressler and Mary Schlott, but I'm realizing that I cannot prove that definitively, given the confusion. Isaac and Mary did have a son Isaac, but which if the many Isaacs is not clear. Therefore, I have broken the chain between Isaac Franklin and Isaac/Mary until I have further evidence.
Please see the discussion at Isaac Franklin Ressler, Sr. for a long discussion of the possibilities.
