Unfortunately, I don't know of an Elizabeth Eschert in my ancestral line. However, if she was born about 1820, she could have been a sister or relative of my great great grandfather, Albert Eschert. He was born in 1824. However, he was born in or near Breslau, perhaps, a small town called Kalisz, in Schlesien. In the 1820s, Schlesien was part of Prussia. Schlesien is better known today as Silesia and is now a part of Poland. Breslau is now Wroclaw.
