Judy,
I have been going through a lot of old messages and found one that you sent me back in 2003. Don't remember whether or not I responded to your Ploch line, so here is what I have.
I have Emma Helena Birchler marrying my great grand uncle, Benjamin Harrison Ploch (b. 1860, d. 06-14-1904). They had the two children that you mentioned, as well as Agnes & Robert Joseph. I do show William marrying Mary Woodward.
As far as your other info beyond Benjamin and Emma's family none of that sounds familiar to me. Please let me know if you have more information.
Thanks,
Bill
