I did not see any of the names you mentioned listed in this book - but this write-up seems to follow one specific line.There are many individuals who are just mentioned if they just so happen to be a child of one of the people (men) in the line the writer was concentrating on.So most of the names for this family don't seem to be listed.I'm sorry I couldn't find anything!
I also have a book called "They Came To Emmaus."(I just moved here 2 years ago, and I love history so I picked it up at the Heritage Days festival last summer.)Anyway, there is no mention of your Trexlers in that either.
If you have other names that you want me to check for, just let me know.I'm sorry I wasn't of much help!!
