No, sorry ... I looked through my database on both my mother & father's side (they are both Millers - totally different lines).No one with those names and no Elizabeth born at that time.
I wonder if your Millers may may have been Amish or Mennonite as the Milan Twp. area had (and still has today) quite a few folks of those religions.Try checking Amish cemetery records in Allen County, IN and also Lancaster Co., PA.Here's a link to a map of PA counties http://www.phmc.state.pa.us/Bah/DAM/counties/county.asphttp://www.phmc.state.pa.us/Bah/DAM/counties/county.asp
Also, you might want to check the Holmes county area in Ohio where the Amish are clustered ... Ashland, Wayne, Stark, & Tuscarawas counties surround Holmes.They may have moved and settled in Ohio before going into Indiana.(My ancestors did!)
