Hi, Mike! It's so nice to meet more family members, especially sharing the name "Pifher," which no one else can pronounce or spell! (My brother is also named Mike, so there's a Mike Pifher here in Michigan).
Do you have a written out family tree? I have one I can send you (I have to search in the basement, but it's there), which traces our branch back to Matthias. That's where I get stuck. I've been researching his name, and found an 1880 census in Ohio that listed him as "Mathias Pfiffer" (how many ways can we spell our name, anyway!), and his wife as Otelia, not "Odelia." Maybe someone couldn't read the census handwriting, or that was the actual spelling. Anyway, it says his home was Cranberry Twp. in Crawford County, and that he was 71 years old that year, and a farmer, and was born in Alsace. Otelia was 67 that year and also lists her parents' birthplaces as Alsace. (I found all this on ancestry.com. I can't afford to pay the account fee there, so I'm unable to pull up the actual record that might list their parent's names.) Lewis is also listed as living with them (age 26 - he was single and helping on the farm). All of this is unconfirmed, but it sure sounds like them!
Right now I'm researching passenger lists from Germany/France to Canada but not finding anything yet, and also more census records of their children. I'll post anything I find out. Anything you can come up with would be great!
