Thanks, Gary. Christian P. Gaa is the key to it. I suspected she was his sister, Philipp and Barbara's daughter, but couldn't document it. Just found Christian's obit a little while ago and it list her as Elizabeth Benefield.
Her father, Philipp, died in 1880 and her aunt, Johanna Schemel nee Gaa, died in May of 1882. Both are buried at St. Peter's in Upper.
In Nov. of 1882 her mother, Barbara nee Gieser, married Christoph Schemel, Johanna's widower.
I just put Christian's obit on my website at:
