I caught your posting because I'm researching the
Dittmar family in Williamsport, PA. There is a
clan of them there that I think are all related,
but I can't yet prove it.
Maybe this will be useful to you.
I saw in "History of Lycoming County" by Meginess
a bio for Justus Dittmar. It has for his wife
"He was married in 1851 to Miss Veronica Steinhilper,
and to this union has been born ten children:"
They are buried in the Washington St. Cemetery.
The stone has
Veronica: Sept. 7, 1826 - Mar. 4, 1894
I could use any information on the Dittmar
family in Williamsport ~1850 - 1900
