Hi Brian,

I looked for variations of spelling of Frentz but found none in the Manning Cemetery records.

I didn't find any Frentz names in the Carroll county cemetery listing.
I found 1 Frantz which is in the Lanseboro Cemetery.

I don't have a list of Audubon county cemeteries so I can't help you there.

I'm presently working on the book "The History of Manning ---1898" and haven't seen the Frentz name so far.
I should have this book converted to web page format in a few days.
