Hi, I have quite a bit of info on JOHANNES LANDAU who married JOHANETTA KATHERINE PFENNIG on 11 Jan 1811.I believe that he was born in Neukircken, Germany--they at least lived there for a time.
Their children were:
Fredricka Katherineb. 21 Oct 1811 Jost Heinuch (Heinrich?)b. 11 Sept 1812 Johanetta Katherine Louiseb. 18 Nov 1814 Johannes Conradb. 10 Sept 1816 Henrietta Louise Whilamineb. 25 Feb 1819 Johann Karl Fredrickb. 10 Dec 1820 Karl Heinrich Wilhelmb. 22 Dec 1822 Karl Christianb. 23 Nov 1825 Henrietta Whilaminab. 11 Feb 1828 Johnnes Christian Fredrickb. 8 Aug 1830
I have some of the childrens info too--such as spouses and children--but it is too much to list here.If you need the info, please contact me.
